The figure belows shows three components of an air-conditioning system, where T3 = 105°F and m3 = 4.5 lb/s. Refrigerant 134a flows through a throttling valve and a heat exchanger while air flows through a fan and the same heat exchanger. Data for steady-state operation are given on the figure. There is no significant heat transfer between any of the components and the surroundings. Kinetic and potential energy effects are negligible. Air Tj = 535°R C,= 0.240 Btu/lb-°R Saturated liquid R-134a T3, ṁ3 Fan Wey =-0.2 hp Throttling valve 4 Saturated vapor P5=P4 P4 = 60 lbf/in.2 T, = 528°R Heat exchanger Modeling air as an ideal gas with constant c, = 0.240 Btu/lb · °R, determine the mass flow rate of the air, in Ib/s. = Tụ i Ib/s
