Assuming US gallons, 346.5 cubic inches per second.

The number will be slightly different for Canadian or Imperial gallons.

MT 600101 oil-less compressor, pdf manual. I specifically would like to know the scfm ratings at 40 and 90 psi.


the air flow from a compressor is determined by the capacity of the pumping system
with a piston type compressor it is the bore by the stroke
in a diaphragm type is it is the diaphragm dia by the stroke
that is the maximum cubic feet of air a minute produced
pressure is the resistance to flow so regardless of the pressure or restriction it will only produce that set air flow at that rpms
do not confuse the flow with pressure as it works like this the greater the restriction the greater the pressure in reserve but the less flow in cubic ft per minute through the restriction
for example a compressor producing 10 cubic feet per minute does that with not restriction but with no pressure
at 25% restriction to air flow the pressure in the tank will now rise to say 25 psi and the flow from the restriction will drop to 8 cubic feet per minute
at 50% restriction the compressor is still putting out 10 cubic feet of air per minute but the tank pressure has risen to 50 psi and the flow from the restriction has dropped to 4 cubic ft per minute
go to the extreme end and the compressor is still producing 10 cubic ft of air per minute , the restriction now allows 100 psi in the tank but the low from the restriction has been reduced to 2 cubic ft per minute
the simple equation is pressure = flow X resistance

If one pumps water from a source at a rate of 7 cusecs cubic meter per second, how many cubic meters of water would be pumped in 24 hours?


7 cubic meters /second = 7 X 60 /minute
= 7 X 60 X 60 / hour= 7 X 60 X 60 X 24= cubic meters per 24 hours or another way
7 X 86400 = cubic meters per 24 hours

How much volume in gallons does ten foot of three quarter inch copper pipe contain?


0.23 gallons. Figured out by assuming the pipe is .75 inches inside diameter. To get the volume, calculate the area of the cross-section with the formula Pi times the radius squared. Which is 0.375 squared times Pi = 0.441786. Multiply that times 12 inches per foot times 10 feet = 53 cubic inches. One gallon = 231 cubic inches.

72in x 29in x 24in how many gallons calculator


72 x 29 x 24 = 50,112 cubic inches / 1728* = 29 cubic feet. There are 7.48 gallons per cubic foot, so the tank is actually 216.92 gallons, assuming the dimensions given are inside measurements. I hope you have a strong stand and floor because the water alone weighs 1735.36 pounds (8 pounds per gallon).

*12 x 12 x 12 = 1728 (cubic inches to cubic feet conversion)

Model #SD-20-2N11CC WATERWAY PUMP (2HP) - Trying to find out how many gallons per minutes pumped on high & low speeds


Rule of thumb for a 2 HP pump using a 2 inch pipe is between 60 and 80 gallons per minute. Factors affecting flow rate is the distance between the pump and the pool, how many bends and turns and of course the condition of the filter. If you need to meet a specific turn-over rate, use the lower number to determine in the event you sould be called on the carpet.

Low speed? I am sorry. I don't know the rule of thumb on this.

You could install a flow meter, available at your professional pool supply. They are easy to install and not a lot of money. Follow the installation instructions as best as you can.

Incidently, comercially speaking, the 'turn over rate' should be around 8 hours for a public pool. Your jurisdiction may have other standards. Commercial pools should run 24 hours a day at that rate during the open season. Turn over rate means all the gallons of the pool should go through the filter in 8 hours, or all the gallons should go through the filter three times per day. Example: 16000 gallons of water in the pool, your filter and pump should be pumping 2000 gallons per hour. Studies show that it actually takes up to 5 days to get every actual 'chunk' of water to go through the filter, so, many of the 'chunks' of water go through the filter multiple times per hour. BTW, I use the word "chunks" in an effort to better paint a mental picture of what is happening. I am not suggesting your water has "chunks" in it.

Thanks for your question @ FixYa.com

Have no chlorine output! Have put in 4 bags of salt, have also cleaned skimmer box basket, pump basket & cartridge filters. Have noticed that pressure is down to 30kpa when is usually 50kpa. Do I need...


Hi again ... Thanks for the Chat yesterday. Have you considered this article: http://www.directpoolsupplies.com.au/webcontent34.htm (click specifically on maintenance of your salt cell) There are lots of good tips here for the pool owner.

I see that this manufacturer wants 4000 ppm salt (4%) minimum to 7000 ppm salt (7%) maximum which is above the standard here in North America. You are in Australia? According to the manufacturer, your cell may be at the end of its life.

Sudden low filter pressure could be a broken lateral in a sand filter (you would probably have sand in the pool) or a hole in a paper filter (no indicator other than low pressure).

Here are some useful numbers for your 4 X 12 X 30 foot pool:

1440 cubic feet or 40.776259104 cu meters
1 cubic foot = 7.5 gallons or
1 cubic foot = 0.0283168466 cubic meters.
1 cubic meter = 264.172052 US gallons.
1 cubic meter = 1000 liters ( you probably know this stuff though)

I calculate your pool to be about 10800 gallons. The actual gallons per foot is really 7.48 (10771.2 in your pool) but we use 7.5 gallons per foot.

One inch in your pool is 225 gallons or 851.71765 L. This will give you some idea about what chemicals you may have to add with one inch of make up water.

If you were in NJ, and a commercial pool, you would have to have a a 8 hour turn over rate with a filter = 60 square feet and your flow rate would be about 22.5 gallons per minute.

Please keep your water balanced with the proper amount of Calcium (about 350 ppm) your pH at 7.4 - 7.6 your TA around 100 (80 min and 120 max) and your salt per manufacturer recommendation, in this case about 5000 ppm. Cyanuric acid around 80 ("Sun screen" for chlorine) and of course Cl around 3 to 4.

I hope you have found this information helpful. Enjoy your pool, while we shiver here in the North East.

How many gallons per minute does this pump move?


From what I can see, under ideal conditions, about 90 gallons per minute for a 1.5 HP, 1.5 inch pump of another manufacturer.

No problem, just looking for gal. per minute flow rate


It uses 1.2 gallons for each wash or rinse action in a cycle.  The water only runs until the 1.2 gallons amount is reached and then that water recycles through the pump for the duration of the action.  Start the dishwasher and time how long it takes until the water stops filling (not the entire time of the action).  Divide 1.2 by the number of minutes including seconds as a decimal fraction (i.e. 1 minute and 30 seconds = 1.5 minutes) to get the flow rate in gallons per minute (GPM).
