A quality mixture of water is contained in a piston cylinder
system at a pressure of 3 bar. The initial volume of the system is
3 m3, and saturated liquid occupies 0.3 m3. Heat is added to the
system and the volume is allowed to triple before a stop is
reached. The final state of the system is at pressure of 30 bar. If
the external pressure is 1 bar determine the followng: (a) The
amount of heat added to...

A mass of 3 kg of saturated liquid-vapor mixture of water is
contained in a piston-cylinder device at 175 kPa. Initially, 2 kg
of the water is in the liquid phase and the rest is in the vapor
phase. An electrical heater is in operation, and the piston rises
until it hits a set of stops, which are set at double the initial
volume. Electrical heating continues until the pressure reaches 500
kPa. Determine (a) the initial and final temperatures,...
