Laboratory measurements have been taken for a single-rod, double-acting linear actuator. The input pressure and flow to the actuator are given by 3000 psi and 38 gpm, respectively. The output force is measured at 4000 lbf and the output velocity is 100 in/s. Calculate the overall efficiency of the linear actuator.

If the pressurized area of the linear actuator in 6.1 is given by 1.43 in2, what is the volumetric and torque efficiency of the actuator?
