Laboratory measurements have been taken for a rotary actuator operating at 40 MPa and 1800 rpm. The torque on the output shaft is measured to be 350 N m and the input volumetric flow rate is 112 lpm. Calculate the overall efficiency of the actuator.

Assuming that the volumetric displacement of the rotary actuator in 6.5 is 60 cm3/rev, calculate the volumetric and torque efficiency of the machine.
