50 kg of Refrigerant R134 are in the state of Satucated moture at a pressure of Pa180 kpa. The quality x is equal to 0.2. It undergoes an expansion process to a superheated state of P2 140 kPa and a temperature Ty-30°C. a) What is the initial temperature of the mixture. bị use the quality x to find the specific volume v of the mixture (so called vavg) and the total volume V1. Find the specific enthalpy of the mixture hy and conclude the total enthalpy Hy. d) Find the variation of enthalpy AH-H-H, between the two states. eFind the variation of volume between the two states
