A pump is used to circulate hot water in a home heating system. 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 lbf/in2, and 180^{\circ}F, respectively; at the exit the pressure is 60 lbf/in2. The pump requires 1/35 hp of power input. Water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 Btu/lb \cdot ^{\circ}R.

Neglecting kinetic and potential energy effects, determine the temperature change, in ^{\circ} R, as the water flows through the pump.

    6. (3 points) A water-based heating system is shown in Figure 5. A pump exerts a constant pressure difference between its inlet and outlet, ΔΡ-12 psi, to circulate hot water across 2 distinct paths. One path contains a single radiator that can be modelled as a pipe with an effective resistance to water flow of Ri-4x 107 kg-m-4 . s-1. The other path has two radiators with effective resistances to water flow given by R2-5x 107kg. m-4-S-1 and R3 3...
