Question

1. A saturated water liquid-vapor mixture with a total mass of 1.3 kg is contained in a piston-cylinder assembly, with the piston initially placed so that the volume of the mix- ture is 1.5 m. The initial temperature of the mixture is 30°C. The piston is then pushed inward until the volume is halved, and the container is heated until the pressure is 400 kPa. Determine Sherleader 306 V Tup V 400 kPa (a) the quality of the mixture for the initial state. (b) the pressure of the mixture for the initial state, (c) the specific internal energy of the mixture for the initial state. (d) the temperature Ty of the mixture for the final state. (e) the specific internal energy uz of the mixture for the final state, Second phone is so
