Q4. A mass of 0.5 kg of saturated refrigerant-l34a is contained in a piston-cylinder device at 200 kPa. Initially, 70% of the mass is in the liquid phase. Now heat is transferred to the refrigerant at constant pressure until the cylinder contains vapour only. (a) Show the process on a P-v diagram with respect to saturation lines. (b) Determine the volume occupied by the refrigerant initially. (c) What type of work is done? What amount (in kJ)? (d) Calculate the total heat transferred to the refrigerant.
