A hydraulic motor must deliver a torque of 70 Nm when rotating at 800 r/min. The maximum system pressure is set by a relieve valve at 15 MPa. The pressure drop between the relieve valve and the motor is 0.8 MPa and the outlet pressure of the motor is 450 kPa. The overall efficiency of the motor is 85% and the volumetric efficiency is 88%. Determine the mechanical efficiency, the displacement volume of the motor, the flow rate supplied to the motor and the hydraulic power supplied to the motor.
