Problem 5(39 points)
0.5 kilograms of water executes a Carnot power cycle. During the isothermal expansion, the water is heated from a saturated liquid to a saturated vapor at a pressure of 2 MPa . The vapor then expands adiabatically to a pressure of 10 kPa where it has a quality of 74.0%. The vapor is then compressed isothermally until its quality is reduced to 24.9%.
a) Sketch the cycle on a p-v diagram, including the vapor dome.
b) Calculate the pressure, specific volume, and specific internal energy at each state.
c) Calculate the heat, work, and change in internal energy for each process, in kJ , and totals for the cycle. Do not invoke Qcycle = Wcycle to solve the problem, but use this to check the validity of your solution.
d) Calculate the cycle efficiency.
e) Calculate the efficiency of a reversible heat engine operating between two reservoirs at this cycle's temperatures.
f) Draw a cycle diagram showing the thermal reservoirs and the values of the flows of heat and cycle work.
g) Evaluate the Clausius inequality for the cycle.
