Repeat Prob. 10-3 for a heat rejection pressure of 10 kPa. Prob. 10-3 A steady-flow Carnot cycle

Question:

Repeat Prob. 10-3 for a heat rejection pressure of 10 kPa.
Prob. 10-3
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.
