I'm trying to calculate flow rate so that I can set the pump RPM to turn over the pool once per day (and ultimately lower my electrical costs). Here are some data points:
Pump: Intelliflo VS-3050
Pool volume: 8500
Current RPM: 2050
Current pressure measured at filter gauge: 14
So, using the equations as best I understand them:
TDH@2050 RPM = 14*2.31+50% = 48.5 (let’s call it 50 for ease of calcs)
To use the Pentair charts, convert TDH@2050 to TDH@3110 using Mark’s equation:
TDH@3110 = 50 * (3110/2050)^2 = 115
But, when I read the Pentair Charts, TDH of 115 is above the maximum operating curve. I'm not sure where to go from here - where did I go wrong? Can the smart people of this forum offer some guidance?
