Hydraulic Equations Calculator

The Hydraulic Equations Calculator available online will allow you calculate hydraulic components operational parameters to achieve circuits’ expected performances. An extensive set of equations is available at your fingertips to size any component available in the Main Hydraulic Library. Examples are shown below.

To name a few:

  • Accumulators: Calculate spring stiffness and maximum stored energy for spring-loaded accumulators, total volume in gas-loaded accumulators and the maximum stored energy and mass in weight-loaded accumulators.
  • Double-acting cylinders:
    • Determine size by calculating piston and rod side area, bore side and rod side pressure, average extend and retract speed, and the mechanical output power;
    • Calculate spring stiffness with spring return or spring extend.
  • Hydraulic fittings: Calculate loss coefficient, laminar or turbulent flow pressure in hydraulic lines, and even fluid line velocity.
  • Hydraulic pumps: Calculate overall efficiency, displacement, effective hydraulic power and hydraulic output power.
  • Hydraulic motors: Calculate displacement, input flow, shaft output power and its nominal speed.
  • Valves: Calculate discharge coefficient of an orifice based on the flow rate, internal diameter, fluid density, diameter ratio and differential pressure.
