You can indeed figure this out using hydraulics formulas.
However, a simpler solution. Run the water into a 5 gallon bucket, and time how long it takes to fill the bucket in seconds.
Use this formula:
Gallons per minute = 300 / TimeToFillBucket
880.57 US gallons per minute
how do i calculate the volumn of backwash in a pool
Find the diameter of the pipe and the pressure and its all simple math after that
The maximum flow rate for a 1 inch diameter pipe is typically around 8-12 gallons per minute. To calculate the maximum volume, you would need to multiply the flow rate by the amount of time the water is flowing.
1 US gallon = 0.133680556 feet^3
Divide it by 60 to get 33.333 gallons per minute.
4.483 US gallons per minute.
To convert 11 gallons per day to gallons per minute, you need to divide by the number of minutes in a day (1440 minutes). 11 gallons/day / 1440 minutes/day ≈ 0.0076 gallons per minute.
The flow would be 2.5 with a meter with 12 inch diameter. This is with a flush at 5.0 FPS.
Use this formula: gallons per minute x 3.785 = liters per minute
96 gallons per minute = about 363.4 liters per minute.
Flow = Pressure / surface S = PI * ( Diameter / 2 ) ^ 2 now you can do the math... I can't tell with gallons, inch and psi.
