An insulated rigid vessel contains 5kg of saturated liquid-vapor mixture of Refrigerant- 134a at 200kPa. At this stage, one-fifth of the mass is in vapor phase and rest is in liquid. Now using an electrical resistance heater, heat is supplied to the contents of the vessel until all of the refrigerant is converted to saturated vapor. Show this process on a P v diagram with respect to saturation lines and determine, 1. volume of the rigid vessel 2. temperature, in...
