Refrigerant 134a enters a well-insulated nozzle at 200 lbf/in.², 170°F, with a velocity of 120 ft/s and exits at 90 lbf/in.² with a velocity of 1500 ft/s. For steady-state operation, and neglecting potential energy effects, determine the temperature, in °F, and the quality of the refrigerant at the exit.

The molar heat capacities of substances varies with temperature. The general function for determining the molar heat capacity is given below; Cp = ( a + b T + c T 2 )R . In case of a gas where a = 3.245, b = 7.108 x10 ^-4 K ^-1 , and c = -4.06 x10^ -8 K ^-2 for temperatures in the range of 300 Kelvins to 1,500 Kelvins.
