CoursHeroTranscribedText: The gure below provides steady-state data for a throttling valve in series with a heat exchanger. Saturated liquid Refrigerant 134a enters the valve at a pressure of 9 bar and is throttled to a pressure of p2 = 1 bar. The refrigerant then enters the heat exchanger, exiting at a temperature of 10C with no signicant decrease in pressure. In a separate stream, liquid water at 1 bar enters the heat exchanger at a temperature of 25C with a mass flow rate of m4 = 4 kg/s and exits at 1 bar as liquid at a temperature of 15C. Stray heat transfer and kinetic and potential energy effects can be ignored. Heat exchanger Saturated liquid R4343 :1th = 9 bar T- = 15C p?=p Water -' 4 T4: 25C p4 = 1 bar Determine: (a) the temperature, in C, of the refrigerant at the exit of the valve. (b) the mass ow rate of the refrigerant, in kg/s
