Q1: A mass of 8 kg of saturated refrigerant-134a mixture with 62 percent quality is contained
in a piston-cylinder device at 240 kPa. Now 150 kJ of heat is transferred to the refrigerant.
a) Develop the governing energy balance equation for the problem.
b) etermine the final phase of the refrigerant.
c) Determine the final temperature of the refrigerant.
d) Show the process on a T-v diagram with respect to the saturation lines.
Note: Frictional effects and piston's mass can be neglegted.
