It is also approximately 7.48 gallons per second.Įach billing unit is 100 cubic feet of water which is equal to 748 gallons.ĬFS stands for Cubic Feet per Second, and it’s a measure of the volume of water passing any given point in a river in one second. One cubic foot per second (cfs) is equal to the discharge through a rectangular cross section, 1 foot wide by 1 foot deep, flowing at an average velocity of 1 foot per second. However, to actually know the gph you must also consider the fuel pressure required for your engine. For example if your pump flows at 50 gph it should be able to support a 500 hp engine (50 x 10 = 500). Water in motion i.e., flowing in streams, canals, pipelines, and ditches, is measured in units of volume per unit of time-gallons per minute (gpm), cubic feet per second (cfs), acre-inches per hour and acre feet per day.Ī good estimator of volume to power is approximately 10 hp per gallon or 2.64 hp per liter. If you can see the fluid flowing, you can measure its velocity, and that means all you need is the area through which the fluid is flowing to calculate the flow rate using the formula Q = A × v. Duplicate the quantity of cubic feet each second by 7.4805 to change over to gallons each second. Measure the pressure inside the tank using a pressure gauge.Subtract the atmospheric pressure from the tank pressure.Multiply the result from step 2 by 2 and divide by the density of water. To calculate GPM from pressure in PSI for water, follow these steps: So if you took 10 seconds to fill a gallon container, your GPM measurement would be 6 GPM (60/10 seconds = 6 GPM). The GPM formula is 60 divided by the number of seconds it takes to fill a one gallon container. * 1 cfs is equivalent to 448.8 gallons of water flowing per minute. * 1 cfs = 1.983 acre-feet per day = 646,320 gallons = 2447 cubic meters of water. * 1 cubic foot per second = 7.4805 gallons flowing by a particular point in 1 second. (60 divided by 5 equals 12 gallons per minute.) Example: The one gallon container fills in 5 seconds. The formula to find GPM is 60 divided by the seconds it takes to fill a one gallon container (60 / seconds = GPM).
How many GPM are in a GPH?ġ gallon per minute(US) = 60 gallons per hour. Multiply the number of gallons per second by 60 to convert to gallons per minute.Multiply the number of cubic feet per second by 448.83 to convert directly from cubic feet per second to gallons per minute. For example, if you start with 42 cubic feet per second, multiply 42 by 7.4805 to get 314.181 gallons per second. Multiply the number of cubic feet per second by 7.4805 to convert to gallons per second.
