1. 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, and (c) the net work output.
