Problem 2. Entropy Balance Using Table of Properties A piston-cylinder assembly contains 3 kg of saturated liquid water at p = 1000 kPa. Heat is added in a constant-pressure process until a quality of 70% is reached. Assume that the heat transfer occurs through a boundary temperature of 215°C. a) Evaluate the work and heat transfer involved in the process. (Ans: W = 405.8 kJ, Q = 4230.8 kJ) b) How much entropy is generated by the process? (Ans: Sgen = 0.67 kJ/K)
