Problem 2Refrigerant-134a enters the compressor of a refrigeration system as saturated vapor at 0.16 MPa, and leavesas superheated vapor at 0.9 MPa and 70°C at a rate of 0.08 kg/s. Determine the rates of energy transfers bymass into and out of the compressor. Assume the kinetic and potential energies are negligible.

A piston-cylinder assembly contains ammonia, initially at a temperature of -20°C and a quality of 60%. The ammonia is slowly heated to a final state where the pressure is 6 bar and the temperature is 140°C. While the ammonia is heated, its pressure varies linearly with specific volume. For the ammonia, determine the work and heat transfer, each in kJ/kg.

Q2// Consider a special ball made of steel (p- 5000 kg/m', Cp- 300 J/kg. k, A= 60 m²). The initial temperature of the ball is 300 K. It is immersed in a large oil tank at 400 K. The convective heat transfer coefficient, h at the sphere surface is 3000 W/m³. k. Assume that there is no radial temperature gradient inside the ball. Use Euler's method to find the temperature of the sphere at t = 15 sec after it was immersed in the oil tank. Use a step size of h= 5 sec. The energy balance equation of the ball is given by the following equation: dT pCp -=-hA(T-T₂) dt
