The figure 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 10°C with no significant decrease in pressure. In a separate stream, liquid water at 1 bar enters the heat exchanger at a temperature of 25°C with a mass flow rate of m4 = 4 kg/s and exits at 1 bar as liquid at a temperature of 15°C. Stray heat transfer and kinetic and potential energy effects can be ignored. Determine: Saturated liquid R-134a at p₁ = 9 bar GLENN Valve -5 2 + P2 T5 = 15°C P5 = P4 (a) the temperature, in °C, of the refrigerant at the exit of the valve. (b) the mass flow rate of the refrigerant, in kg/s. -Heat exchanger 3 www www. m4 Water T₁ = 25°C P4 = 1 bar P3= P2 T3 = 10°C
