Example: How much oil will be produced by a 2.5 cubic inch pump operating at 1200 rpm? Formula: RPM x Displacement 

Log Splitter Hydraulic Pump Flow Rate CalculatorRevolutions Per Minute (RPM) x Displacement in3 ÷ 231 = gpm · Flow (GPM) = (1500 x 2.75 = 4,125 ÷ 231 = 17.85 · RPM x Pump Displacement ÷ 231 · 231 x GPM ÷ RPM.

Hydraulic Pump FormulasDISPLACEMENT = FLOW RATE(GPM) x 231. PUMP RPM ; CIPR = GPM x 231. RPM How To Calculate Hydraulic Pump and Motor EfficiencyFeb 2, 2015 — Theoretical flow is calculated by multiplying the pump's displacement per revolution by its driven speed. So if the pump has a displacement
