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 the system; and (b) the amound of work performed by the system.
