Web11 dec. 2024 · By using water pressure as a starting point, then applying the Bernoulli equation, you can calculate the flow rate. Step 5 – The flow rate of water in gallons per … WebThe relevant formula for establishing the flow rate of a specific centrifugal pump when impeller diameter is constant is expressed as: Q₁/Q₂ = (N₁/N₂) Where Q = flow rate, N = shaft speed, 1 = current or before, and 2 = new or after By using this formula, we can determine how the flow rate varies when changes are made to the shaft speed.
Web9 jan. 2024 · Note the motor speed in rpm that you wish to convert to GPM. Divide this value by the nominal pump motor speed and record your answer. For example, if the required motor speed is 900 rpm and the nominal speed is 1,000 rpm, the answer is 0.9. Multiply your answer by the nominal flow rate for the pump to give the converted flow rate.
