US gallon per minute, gpm Definition Conversion chart, cfs to gpm, gpm to ft3/s cfs, ft3/s. While there is no official symbol for the gallon (as there are for SI units), gal is in common use. Three significantly different sizes are in current use: the imperial gallon defined as 4.54609 litres, which is used in the United Kingdom, Canada, and some Caribbean nations the US gallon defined as 231 cubic inches (3.785 L), which is used in the US and some Latin American and Caribbean countries and the least-used US dry gallon defined as 1⁄ 8 US bushel (4.405 L). The gallon ( / ˈ ɡ æ l ə n/) is a unit of measurement for liquid capacity in both the US customary units and the British imperial systems of measurement. You can also go to the universal conversion page. To switch the unit simply find the one you want on the page and click it. US gallon per minute, gpm Definition:ĭefinition of US gallon per minute, gpm provided by WikiPedia: This is a conversion chart for cubic foot per second (U.S.
Its volume is 28.3168 liters or about 1⁄ 35 of a cubic meter.Īt 60 ☏, a cubic foot of water weighs 62.36630 pounds (28.28888 kg). It is defined as the volume of a cube with sides of one foot (0.3048 m) in length. The cubic foot is an imperial and US customary (non-metric) unit of volume, used in the United States, and partially in Canada, and the United Kingdom. Gpm: US gallon per minute Conversion formulas Cubic feet per second, US gallon per minute (cfs, ft3/s, gpm) Cubic feet per second, cfs, ft3/s Definition:ĭefinition of Cubic feet per second, cfs, ft3/s provided by wikipedia: Now let's see if using the psi to gallons per minute calculator can make our life easier.Conversion formulas Cubic feet per second, US gallon per minute (cfs, ft3/s, gpm): To convert cubic foot per second to gallons per minute, we multiply by 444.8: Multiply the velocity by the cross-sectional area of the pipe:Īrea = 3.14 * (0.20833 / 2) 2 = 0.03409 ft 2 1 cubic foot per second ( ft 3 /sec ) 448.83 gallons US per minute ( gal/min ). Taking the square root of the above value: This on the web one-way conversion tool converts flow units from cubic feet per second ( ft 3 /sec ) into gallons US per minute ( gal/min ) instantly online. (8251 * 2) lbs/ft 2 / 62.4 lbs/ft 3 = 264.46 Convertir des units de Flux: mtres cubes par second m3/s,litres per minute l/min, pied cubes par minute (cubic feet per minute) cfm, pied cubes par heure (cubic feet per hour) cfh, pied. Now we multiply the difference in pressure by 2 and divide the result by the density of water ( 62.4 lbs/ft 3). To convert from pounds per square inch to pounds per square foot we will multiply the result by 144: The pressure at the exit point will be equal to the atmospheric pressure, i.e., 14.7 psi.įirst we calculate the difference between the pressure inside the tank ( P 1) and at the exit point ( P 2): Let the pressure inside the tank be 72.0 psi. Let us see how we can calculate the flow rate of water as it exits from a tank through a pipe of diameter 2.5 inches.
CONVERT GPM TO CFS HOW TO
In the next section, we will see how to calculate GPM from pressure. In other words, as the speed of a moving fluid increases, its pressure drops and vice-versa.

Wire to Water Efficiency: Overall Efficiency Water Horsepower x 100 Electrical Horsepower. Water Horsepower i.Q (flow gal/min.) x H (Head in ft.) 3960. P 1 + 1/2 * ρ * v 1 2 = P 2 + 1/2 * ρ * v 2 2 g.Motor Horsepower Brake Horsepower Motor Efficiency. (Source: )įor a fluid flowing at a constant depth/height, the above equation changes to: P 1 + 1/2 * ρ * v 1 2 + ρ * g * h 1 = P 2 + 1/2 * ρ * v 2 2 + ρ * g * h 2 A typical geometry used for the derivation of Bernoulli's equation. When the fluid flows through a pipe that has varying diameter and height, the pressure and energy densities at two locations along the pipe are related as: The potential energy density is calculated with the use of a modified potential energy equation, with density instead of mass of the fluid. Bernoulli's equation states that for an incompressible, frictionless fluid, the sum of pressure ( P), kinetic energy density, and potential energy density is constant, i.e.:
