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 Ibf/in.2, and 180F, respectively; at the exit the pressure is 90 Ibf/in.2 The pump requires 1/15 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 R. Neglecting kinetic and potential energy effects, determine the temperature change, in R, as the water flows through the pump. AT = R the tolerance is +/-5%
