Here you can find the online calculations for Pump-Motor in close loop.
These calculations are for variable displacement pump and fixed displacement motor.
These calculations can help you to estimate the pressure losses, and flow velocity in the conduit (hose, pipe or tube) and check/correct conduit ID.
These calculations can help you to figure-out conduits (hoses, pipes or tubes) parameters (ID sizes, piston speed, flow velocity and cylinder’s force) for any qty of cylinders connected in parallel circuit.
Here you can find the online chart which let you easy adjust any flow or pressure valve using its settings range and the available number of turns.
