A cylinder having an initial volume of 3 m3 contains 0.1 kg of water at 40° C. The water is then compressed in an isothermal quasi-equilibrium process until it has

a quality of 50%. a) Draw T-V and P-V diagrams (20 points). b) Calculate the work done in the process splitting it into two steps (60 points). c) Determine the internal energy u (kJ/kg) of water at final state. (20 points) Assume the water vapor is an ideal gas during the first step of the process.
