WebJun 29, 2024 · 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.
