Calculating Your Pump’s Flow Rate Sintech Pumps

29-06-2021  Calculate flow rate manually by collecting fluid – You can collect the fluid at the output of the pump system using a bucket or vat. Measure the collected fluid, the time taken to collect it, and reverse engineer to find the flow rate. The formula for calculating the flow rate: Flow rate = Volume of Liquid Collected / Time Taken

Centrifugal Pumps Fluid Flow Practical Calculations

4. Volumetric Flow Rate The volumetric flow rate (Q - ft³/s) can be calculated as the product of the cross sectional area (A - ft²) for flow and the average flow velocity (v – ft/s). Q = A x v Example 6: A pipe with an inner diameter of 4 inches contains water that flows at an average velocity of 14 ft/s.
