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/in.2, and 1808F, respectively; at the exit the pressure is 120 lbf/in.2 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 ? 8R. Neglecting kinetic and potential energy effects, determine the temperature change, in 8R, as the water flows through the pump. Comment on this change.
