Problem 2: Note that this problem is similar to Problem 4 from the previous homework. However, we wish to solve the same problem with the concept of entropy we learned in chapter 6. One kilogram of water executes a Carnot power cycle. During the isothermal expansion, the water is heated until it is a saturated vapor from an initial state where the pressure is 10 bar and the quality is 20%. The vapor then expands adiabatically to a pressure of 3 bar. a. Sketch the cycle on T-s coordinates. b. Evaluate the thermal efficiency. C. Evaluate the quality of steam in all states.
