A mass of 5.5 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder at 101.325 kPa. Initially, 2.3 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 21 percent. Determine: a) the initial...

A piston cylinder device initially contains 1.2kg of saturated liquid water at 220oC. Now, heat is transferred to the water until the volume quadruples and the cylinder contains saturated vapor only. Determine (a) the final volume of the tank, (b) the final temperature (c) the final pressure, and (d) the change in internal energy of the tank. To check your work, enter the final pressure in kPa in the box below. Also, sketch this process on a T-v diagram.
