Can anyone tell me how Automatic Gold Dredgers work?




Man-eo


I have been trying to figure out how something that separates the gold from the mud/sand work??

and i am getting NO WERE, lol.

Can someone explain it to me?



Answer
No prob, I live in gold country. There are the floating self sustaining dredges. They are fairly small dredges on floats. They are usually anchored. There's a suction hose that acts similarly to an automatic pool cleaning device. It moves around the bottom and deposits the silt i.e. mud/sand into a shaker box where water is continually run through. Since gold is more dense/heavier than sand/mud it tends to not be washed away. It all has to do with the periodic table of elements and their mass. What it comes down to is a filtering action where the heaviest particles stay and the lighter slag is washed away. There's also a less autonomous system where a diver uses the suction hose and manually vacuums the bottom. Hope it helps.

Is a salt water pool better than fresh water for your health,and also for cleaning out pool after?










Answer
I reckon you're asking about salt generators.
There are many out on the market and their popularity has grown over the last 10 years. About half of all new pools being installed these days are set up with a salt generator.
There's something you should know about these generators. Most people believe that this is a non chlorine system. It actually is chlorine based. The idea behind these generators is to change salt into chlorine. Chlorine is actually a form of salt that's a little more "energized" than normal table salt. It's that property that allows it to effectively sanitize a pool.
With a salt generated pool, the actual salinity of the water is quite low. So low that unless you have exceptional taste buds, you won't taste it. You won't float any differently either than in fresh water.
There are a number of advantages with going salt. First and foremost is the "feel" of the water. A salt generated pool is a lot easier on eyes and skin than a traditionally chlorinated pool. The water is "softer". Because the chlorine produced by the unit is in a low constant dose, there's no high amount of chlorine in there to bother a person but it's still high enough and produced almost constantly, to keep the pool looking good. Another reason to go salt is the cost savings over time. These units are expensive initially but save a lot of money in chemicals that you don't need to add anymore. No more shock unless you get into trouble, less acid and less TA adjustment chems are needed as well. Salt generated pools tend to stay pretty stable in the water chemistry department. More so than any other form of sanitizer system. These systems are also automatic. You basically just set them and forget them with just a once a week check of the LCD screen on the control panel to make sure there's no issues. Maintenance usually just consists of a once a year cell cleaning which doesn't take long and the home owner can do this themselves.
The one drawback they have is the need to check your stabilizer levels a little more often than you normally do with a normal chlorine pool. You aren't using pucks anymore ( they have stabilizer in them) and you'll have to compensate for that when required. You'll also have to keep an eye on your salinity and add salt if required. This will happen once or twice per year with a sand filtered pool ( you're backwashing), only once as a rule with a cartridge or DE filter.
I disagree with what the other poster has said regarding retrofitting an older pool with salt. You can do it no problem at all. The only thing that would hinder that is if the pool were on Bromine before switching to salt/chlorine. In this case you'd have to dump the water since Bromine isn't compatible. If you're on chlorine now, it's not an issue. The only other thing I can think of that may be an issue is the pool's electrical grounding. If the pool was built properly it will be properly electrically bonded and there is no issue. If the pool builder cut corners and didn't bond the structure, ladders etc then there might be a corrosion issue 10 years down the road. It's easy enough to fix before the installation of the salt unit.
I also disagree with the other poster in that you DON'T need to still add chlorine. If the unit was sized and installed properly, it will work just fine by itself with no need for any additional chlorine unless you have a hundred kids suddenly using the pool and weren't prepared for it. Preparation is a simple matter of turning a knob on the control unit to up the amount of sanitizer produced before the party. That's it.
As a former pool tech and I was given the choice on what to use for a sanitizer system, I'd go salt in a heart beat. Less hassle, less overall cost and more enjoyment of the pool. So the answer to your question is yes salt generated pools are healthier and you're going to be cleaning any type of sanitized pool out. They all get dirty.

How often should you shock your pool?




rebeccasta


How often do you shock your pool? The pool company said if you have a large amount of poeple swimming to do it once a week, however it's just my husband and I who swims in it and with our schedules it's hardly ever at the same time. Should we be shocking that often. We have a 16 by 32 inground pool and it has one of those automatic cholorine feeder in it where you put the pucks in. I was told that too much chlorine will ruin the liner. We are replacing our liner in a couple weeks because the corners of the liner were ripping away from the pool. Just wondered since we have the automatic chlorine feeders and it's just my husband and I swimming in it how often we should shock it.


Answer
I have operated commercial pools for ten years,i shock at ten ppm.once in the spring and once in the fall. The only time their has been an issue is when i go on vacation.Then the pool is neglected and i get alge or cloudy water. there is a company called taylor technologies.they make a test kit no.k-2005. This kit has a booklet explaining water chemistry,and tables to treat your pool.Its not that hard at all. If you keep your chlorine at 2-3 parts per million. Problems arise when people neglect their pool,if bacteria is allowed to grow then you do need to shock. If you do your home work pools are easy.Keep the filter clean the chlorine good and the water ballanced and you will have no issues. Sometimes i think pool suppliers want to sell lots of chemicals.I have answered pool questions before and got beat out by a cleaver sounding answers that were not correct. I'm not sure if i can do this,my e-mail is yaket2003 @yahoo.com. If you have a question ask.I stand by this answer100% With that said without an accident or special event you shouldn't need to shock more than twice a year.The need to shock arises when the dead chlorine over powers the good this is explained in the book. You can test to determine this,many home pools are neglected,I believe thats why people shock so much.

how much does an inground pool cost?




limetemple


medium size


Answer
Medium size would be an 18 x 36. Costs of construction can vary enormously. Expect that size pool to start at about 18,000 canadian dollars for a vinyl inground. A concrete (gunite) pool would be about 28 grand to start.
Extra costs can be incurred if the access to the dig is difficult, material has to be trucked father away to dump, if the area the dig is in is in a high water table or is very rocky.. The toys you want with the pool, like water falls or adjacent hot tubs. The pool equipment packages can vary from basic to hi tech advanced remote wall unit controls in the house for heat, automatic pool cleaner controls and even one touch and forget, timed pool fill valves.

Regression Problem- Confim my Anwers Please?




sabunabu


Please see the below and my answers-- please let me know if you disagree and also if you know the answers to the 2 questions I don't. Any help is greatly appreciated.

PoolVac, Inc. manufactures and sells a single product called the âSting Ray,â which is a patent-protected automatic cleaning device for swimming pools. PoolVacâs Sting Ray accounts for 65 percent of total industry sales of automatic pool cleaners. Its closest competitor, Howard Industries, has captured 18 percent of the market.

Using the last 26 months of its sales data, PoolVac wishes to estimate demand for its Sting Ray. Demand for Sting Rays is specified to be a linear function of its price (P), average income for households that have swimming pools in the U.S (MAVG) and the price of the competing pool cleaner sold by Howard Industries (PH). The general linear form of the demand function

Qd = a + b P + c MAVG + d PH.

The attached computer printout presents the regression output from 26 observations (monthly data) on the price charged for a Sting Ray (P), average income of households with pools (MAVG), and the price Howard industries charged for its pool cleaner (PH).
âââââ ââââââââââââââââââââ
The printout of part of regression output from Minitab for the empirical demand is below:

ââââââââââââââââââââââââââââ
1. An estimated demand equation for PoolVac is:
Qd = 2728.8-10.758P+0.021420M+3.166Ph


2. Evaluate the statistical significance of the three estimated slope parameters using a significance level of .05 or 5 percent (you can either use p-values or do a t-test).Please, explain how you decided each parameter was statistically significant or not.

Since the P values of all 3 variables are within the 5% confidence interval, each variable should be considered as staristically significant in determining the demand of the pool vacuums.


3. What is the exact level of statistical significance for estimated slope parameters on price, average income of household and price of related good? Please, explain how you know.

We should look at the P value for each of the slope parameters and in doing so, we find that price is 100% significant, average income (Mavg) is 96.6% (100-.034) and price of competition (Ph) is 97.2% significant (100-.028).


4. Discuss the appropriateness and/or interpretations of the algebraic signs of the three slope parameters, based on your theoretical expectations. Interpret the numerical values of the three slope parameters in the context of this regression.


5. Now evaluate the overall fit of the estimated (sample) regression equation to the data.

a. What percentage of variability in Qd (linear) is explained by a model? Does it indicate a good overall fit? Please, explain.


b. Verify whether the overall regression equation is statistically significant, another words, verify the goodness of overall fit .What is the exact level of significance for the entire regression equation?

Looking at the F stat which is 211.1, we can say the overall regression equation is significant since the absolute value is large. Also, the P value is 0 so there is no chance that this regression equation doesnât explain the relationship between the given variables and quantity demanded.



Answer
All of your answers are good. To say that the F statistic has a large absolute value is a little vague; one would generally either consult an F table to the appropriate threshold value or just look at the P value in the computer output. On the other hand, it isn't wrong, and if your instructor taught it that way you should leave it in.

Regarding the questions you haven't answered, number 4 refers to the direction of the effects on your dependent variable that come with changes in the independent variables. You should look at your coefficients and consider what would happen if you changed the values in your variables. For example, if the price of the product goes up, demand for the product goes down because of the negative coefficient associated with the price variable. If this seems confusing, try plugging in some different values into the equation and calculating the result. The negative coefficient makes sense, because people are going to be less interested in buying something if its more expensive. The question is asking you to evaluate both the actual effects on demand and the expected effects for each of the variables.

Question 5a refers to the R-squared statistic (R-Sq), which is the percent of explained variability as mentioned in the question. Yours is quite high.

what is the single greatest use for salt?

automatic pool table cleaner on Videos in Pools
automatic pool table cleaner image



Haley





Answer
there are actually many great uses of salt which benefits us in many ways like:

ALUMINIUM PURIFICATION Salt is used as a flux. The salt sits on top of the molten aluminium in molten salt form, this removes iron and other metals from aluminium leaving pure metal.

BREAD AND PASTRY Salt is used to give added flavour to bread and pastry. The main requirement here is that the product, either flossy or superfine, is clean and free from any extraneous matter. Salt also performs a function in controlling the rate at which the yeast works in the dough, giving a better texture to the bread.


CANNING OF MEAT AND VEGETABLES Salt is added to the products during processing and it is essential in these cases that the salt be free of grit, and particularly free of any specks or iron particles as these show up in the finished product.

CAUSTIC/CHLORINE MANUFACTURE The conversion of salt to form caustic soda and chlorine requires a crude salt with very high chemical purity. Salt is dissolved to form brine and the impurities are removed chemically before the brine passes into the electrolytic cells.

CHEESE MANUFACTURE Most cheese today is made on automatic machines and salting must be carried out in a continuous process. The salt used must be extremely dry at all times and contain virtually no fines beyond 60 mesh.

DRILLING Salt is used to mix with boring mud which is pumped down bore holes to form a wall when drilling through gravel or sandy material which will not stand up on its own.

FISH & MEAT CURING This is usually carried out by dissolving salt to form a strong brine to act as a pickle. The products may be placed in the pickle, or in many cases the pickle is pumped into the actual meat (such as in the case of bacon and ham). Salt for these purposes should be refined grades, clean and of high quality.

GENERAL COOKING Fine salt is used for all sorts of cooking and is similar to table salt, without the addition of Sodium Silico Aluminate.

HIDE CURING Hides and sheep skins are normally salted with a reasonably low quality salt. Hide salts are usually only washed grades but contain certain additives such as boric acid, to keep the hide as light a colour as possible. Other additives are naphthalene and sodium fluoride.

POTTERY PRODUCTION Salt is used to form the very smooth glaze on clay tiles or pottery ware. After a kiln of tiles reaches a yellow to white heat, salt is then fed on to the fire. The salt vaporises and passes on to the surface of the tile, actually forming a glass surface.

SOAP & GLYCERINE MANUFACTURE Fats and oils are saponified by heating with caustic soda to produce soap and glycerine. The soap is "grained" or "salted out" from solution by adding salt or strong brine.

SWIMMING POOLS Swimming pool salt is designed specifically for use with salt pool chlorinators

SYNTHETIC RUBBER MANUFACTURE Synthetic rubber is produced in the form of white latex to which salt is added as an emulsifier. Salt for this purpose is in crude form, of medium quality.

TABLE SALT This is a specially prepared salt for domestic purposes, with small, even crystals. Sodium Silico Aluminate is added as a free flowing agent. Table salt also comes in iodised form.

TEXTILE DYEING Salt is added to the dye baths during the process mainly to make the dyes fast. Flossy salt is the grade most commonly used in this process.

WATER SOFTENING Salt is used in both industrial and home water softening units. The purpose being to regenerate the resins which pick up the objectionable salts in the normal water supply. Salt for this purpose is usually a washed or refined grade. A similar type of salt is used for making a brine for brine cooling systems.

OTHER USES Other uses of salt include butter manufacture, soil stabilisation, tempering of steel, fertilisers and weed killers, and pine board manufacture.

How often should you shock your pool?




rebeccasta


How often do you shock your pool? The pool company said if you have a large amount of poeple swimming to do it once a week, however it's just my husband and I who swims in it and with our schedules it's hardly ever at the same time. Should we be shocking that often. We have a 16 by 32 inground pool and it has one of those automatic cholorine feeder in it where you put the pucks in. I was told that too much chlorine will ruin the liner. We are replacing our liner in a couple weeks because the corners of the liner were ripping away from the pool. Just wondered since we have the automatic chlorine feeders and it's just my husband and I swimming in it how often we should shock it.


Answer
I have operated commercial pools for ten years,i shock at ten ppm.once in the spring and once in the fall. The only time their has been an issue is when i go on vacation.Then the pool is neglected and i get alge or cloudy water. there is a company called taylor technologies.they make a test kit no.k-2005. This kit has a booklet explaining water chemistry,and tables to treat your pool.Its not that hard at all. If you keep your chlorine at 2-3 parts per million. Problems arise when people neglect their pool,if bacteria is allowed to grow then you do need to shock. If you do your home work pools are easy.Keep the filter clean the chlorine good and the water ballanced and you will have no issues. Sometimes i think pool suppliers want to sell lots of chemicals.I have answered pool questions before and got beat out by a cleaver sounding answers that were not correct. I'm not sure if i can do this,my e-mail is yaket2003 @yahoo.com. If you have a question ask.I stand by this answer100% With that said without an accident or special event you shouldn't need to shock more than twice a year.The need to shock arises when the dead chlorine over powers the good this is explained in the book. You can test to determine this,many home pools are neglected,I believe thats why people shock so much.
