Consider a heat engine is operating on a steady‐flow Carnot cycle with water as the working fluid. The water mass flow rate in cycle is 0.5 kg/s. The cycle maximum per minimum absolute temperatures ratio is 2.5. The quality of water is 1 at the beginning of the heat‐rejection process and 0 at the end and the ambient temperature is 35°C. Show the cycle on a T‐s and P‐v diagrams relative to the saturation lines, and determine (a) the thermal efficiency, (b) the pressure at the turbine inlet, (c) maximum temperature, minimum pressure (d) the network output, (e) the entropy changes in all processes, and (f) the actual network output with second law efficiency of 45%.

Question
Consider a heat engine is operating on a steady‐flow Carnot cycle with water as
the working fluid. The water mass flow rate in cycle is 0.5 kg/s. The cycle
maximum per minimum absolute temperatures ratio is 2.5. The quality of water
is 1 at the beginning of the heat‐rejection process and 0 at the end and the
ambient temperature is 35°C. Show the cycle on a T‐s and P‐v diagrams relative
to the saturation lines, and determine (a) the thermal efficiency, (b) the
pressure at the turbine inlet, (c) maximum temperature, minimum pressure (d)
the network output, (e) the entropy changes in all processes, and (f) the actual
network output with second law efficiency of 45%.
