Moved from old thread HERE
Please help me understand why there is no need to know the flow rate.
If I have a 20,000 gallon pool and can run the pump 20 hours a day (when electricity is cheaper and solar is on). If I assume one turn per day (it is residential with a pool cover and no debris from trees), wouldn't I need 20,000/(20 hours*60 minutes/hour) = 16.7 GPM?
I would have thought that the flow rate is the most important factor, as it determines how much water is filtered per unit time.
I also thought that flow rate would be directly proportional to pump speed (it is a volumetric movement of water).https://www.engineersedge.com/fluid_flow/pump_laws.htm#:~:text=These%20laws%20state%20that%20the,cube%20of%20the%20pump%20speed.
