VARIABLE. Fluid Pressure - P · Fluid Flow Rate - Q · Fluid Power in Horsepower - HP ; WORD FORMULA WITH UNITS. (PSI) = Force (Pounds) / Area ( Sq. In.) GPM= Flow ( 

If you have the horsepower HP and the hydraulic motor speed in ⍵ in rpm, you can find the torque T in inch-pounds using this formula: T = HP x 63025 / ⍵ If you a hydraulic motor with 225 hp and a speed ⍵ of 1,500 rpm, then the resulting torque would be T = 225 * 63025 / 1500 = 9,454 inch-pounds Pressure and Displacement

Hydraulic Motor Calculations -Hydraulic motor.jpg . GPM of Flow Needed for Fluid Motor Speed: Motor Displacement x Motor RPM ÷ 231 . Example: How much torque is developed by a motor at 12 horsepower and 1750 rpm? Horsepower = 12. RPM = 1750. Horsepower x 63025 ÷ RPM = 12 x 63025 ÷ 1750 = 432.17 inch pound

Most hydraulic power units do not continuously operate using the same power load, and their flow and pressure levels are constantly changing as various actuators move during the machine cycle. As an example, during a single cycle, a hydraulic pump might shift from 10Hp for ten seconds to 15Hp for five seconds, 4Hp for thirty seconds, 12Hp for

The hydraulic Horse Power can be calculated as: Ph (hp) = Ph (kW) / 0.746 (2) where Ph (hp) = hydraulic horsepower (hp) Or - alternatively Ph (hp) = qgpm hft SG / (3960 η) (2b) where qgpm = flow (gpm) hft = differential head (ft) SG = Specific Gravity (1 for water) η = pump efficiency Example - Power pumping Water
