a Refrigerant 134a enters a horizontal pipe operating at steady state at 40°C, 3.2 bar and a velocity of 40 m/s. At the exit, the temperature is 50°C and the pressure is 240 kPa. The pipe diameter is 0.04 m. Determine (a) the mass flow rate of the refrigerant, in kg/s, (b) the velocity at the exit, in m/s, and (c) the rate of heat transfer between the pipe and its surroundings, in kW. Also find the entropy generation rate (kW/K) if Tb = 30C
