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 180°F, respectively; at the exit the pressure is 60 lbf/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
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 = 1
°R
