A steady flow Carnot cycle uses water as the working fluid W

A steady flow Carnot cycle uses water as the working fluid. Water changes from saturated liquid to saturated vapor as heat is transferred to it from a source at 280 degree C. Heat rejection takes place at a pressure of 25 kPa. Determine the thermal efficiency, eta_th = percent the amount of heat rejected q_out = kJ/kg and (c) the net work output w_net = kJ/kg Round your final answers to one decimal place. Assistance
