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 250°C. Heat rejection takes place at a pressure of 20 kPa. Show the cycle on a T-s diagram relative to the saturation lines, and determine
(a) The thermal efficiency,
(b) The amount of heat rejected, in kJ/kg, and
(c) The net work output.
