4.29 Refrigerant 134a flows at steady state through a horizontal tube having an inside diameter of 0.05 m. The refrigerant enters the tube with a quality of 0.1, temperature of 36°C, and velocity of 10 m/s. The refrigerant exits the tube at 9 bar as a saturated liquid. Determine (a) the mass flow rate of the refrigerant, in kg/s. (b) the velocity of the refrigerant at the exit, in m/s. (c) the rate of heat transfer, in kW, and its associated direction with respect to the refrigerant. __________________________________________________________________________________________
