The calculation of liters per minute (LPM) for a hydraulic motor at a specific RPM is determined solely by the motor's displacement and the desired RPM. The pressure of the oil in the circuit does not influence the flow rate calculation, as hydraulic oil is treated as incompressible in practical applications. Torque is directly influenced by the pressure, confirming that while RPM is a function of LPM, pressure plays a critical role in torque generation.
