How to Calculate gpm through a 1in pipe at 10fts?
The first thing to do is find the volume of liquid in 10 feet of the pipe.A 1" diameter pipe has an area of 0.785398163397448 square inches.10' = 120"So 10' of 1" pipe holds 94.24777960769376 cubic inches - let's round it to 94.2594.25 per second = 5655 per minuteAn Imperial gallon measures 0.16054365 cubic feet.1 cubic foot = 1728 cubic inches0.16054365 cubic feet = 277.4194272 cubic inches - let's round that to 27.45655 / 27.4 = 20.3857 - call it 20.4 Imperial gallons per minuteA US gallon measures 0.13368056 cubic feet1 cubic foot = 1728 cubic inches0.13368056 cubic feet = 231.00000768 cubic inches - let's call that 2315655 / 231 = 24.4805 - call it 24.5 US gallons per minute
How many gallons does a 8 foot round 30 inch deep pool hold?
Assuming it is round, (1) convert all measurements to feet. (2) Use the formula for the volume of a cylinder to get the volume in cubic feet. (3) Convert from cubic feet to gallons. As an alternative, you can also convert all measurements to inches, and in the final step, convert from cubic inches to gallons.
