A vessel is divided by a frictionless piston into two equal parts of 0.4 m3 each, as in Figure P5.39. One part contains steam at 700 kPa and quality x = 0.16, whereas the other part contains air. The vessel is cooled slowly by a thermostatic bath, at the highest possible temperature, till it contains saturated liquid. Steam Air FIGURE P5.39 a. Find the mass of steam and that of air in the vessel. b. Find the final pressure of air. c. Find the work and heat interactions of the steam in the process. d. Find the temperature of the bath. e. Find the change in entropy of the steam.
