Determining flow rate from pressure
WebJun 8, 2024 · So, when pressure in the pump causes more load on the motor, it slows down. When the motor slows down, the flow rate drops at the same percentage. A motor that operates at about 2000 RPM at low pressures will typically slow down to about 1750 RPM when the pump is pressurized to the maximum rating. It stands to reason, then, … WebJan 3, 2024 · To calculate PSI from GPM and pipe diameter, proceed as follows: Calculate the cross-sectional area of the pipe using the given diameter. Divide the flow rate measured in GPM by the area and take the square of the result. Multiply the value from step 2 with the density of water and divide by 2. Add the atmospheric pressure to the result from ...

http://irrigation.wsu.edu/Content/Calculators/Drip/Drip-Line-Rate.php WebGas will always flow where there is a difference in pressure. Δp = (p 1 – p 2) > 0. The intensity of the gas flow, i.e. the quantity of gas flowing over a period of time, rises with the pressure differential. In the case of viscous flow, however, this will be the case only until the flow velocity, which also rises, reaches the speed of sound.
