The figure belows shows three components of an air-conditioning system, where 105°F and

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.

Modeling air as an ideal gas with constant c_p = 0.240 Btu/lb · °R, determine the mass flow rate of the air, in lb/s.
