In this video we will be discussing how to calculate TDH or Total Dynamic Head. When selecting a water treatment system you must know the well pump flow rate in gallons per minute. 0007 (this is a 'rule-of-thumb' calculation) Example: How many horsepower are needed to drive a 5 gpm pump at 1500 psi? GPM = 5 PSI = 1500 GPM x PSI x. Pump ratio x GPM @ 100 psi = CFM. 14 x 60 = 8. Calculating Fuel Requirements By Chris Myer. To calculate the days required to fill a pond with your solar pump divide the numbers in the table on the right by the estimated Gallons Per Day for your selected pump (assuming your well can support that GPM). In this video, This Old House plumbing and heating expert Richard Trethewey explains how a recirculation line can save energy, money, and time. The total design flow rate is (12 coils x 2 gpm) or 24 gpm per riser. You cannot directly convert PSI to GPM. GPM = Oil flow in gallons per minute CIR = Cubic Inch (in3) per Revolution RPM = Pump revolutions per minute Volume required (gpm) = Volume Displaced x 60 Time (s) x 231 Flow rate (gpm) = Velocity (ft/s) x Area (in2) 0. Typical levels of free chlorine (or residual chlorine) in drinking water are 0. Connect each dot with a line.
