A steady flow of 15 kg/s of high-pressure liquid oil drives a hydraulic motor at the steady-state-steady-flow conditions shown below. Heat loss from the motor to the surroundings is 5 kW. This is not a quasi-equilibrium process. Use standard gravity, g = 9.81 m/s2.
Find the diameter of the exit pipe, D2 = ________ (m) and the power output, Wcv & out = _________ (kW).
