  • Hydraulic Calculations-Hydraulic System Design

    The hydraulic power supplied by a pump is: Power = (P x Q) 500 - where power is in kilowatts [kW], P is the pressure in bars, and Q is the flow in litres per minute. Example: if a pump delivers 180 litres/minute and the pressure is 250 bar, then the hydraulic calculation for prime mover power of the pump is: Power = (250 x 180) 500 = 90 kW **.
