The figure belows shows three components of an air-conditioning system, where T3
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.

Water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. The inlet pressure and temperature are 14.7 Ibf/in.?, and 180°F, respectively; at the exit the pressure is 90 Ibf/in.2 The pump requires 1/25 hp of power input. Water can be modeled as an incompressible substance with constant density of 60.58 Ib/ft and constant specific heat of 1 Btu/lb · °R.
