Calculations for LMP for certain RPM of hydraulic motor

[siddharth23]

If I want the output of a hydraulic motor to be of a specific RPM, then knowing the pressure of the oil in the circuit, how does one calculate the LPM of the pump corresponding to that RPM?

 

[etudiant]

The flow in LPM is set by the RPM of the motor and its displacement. The pressure does not enter into the calculation, as the oil is incompressible for all practical purposes.

So RPM of the motor depends only on the LPM of the oil?
And pressure is the deciding factor in the torque, right?
