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.?, and 180°F, respectively; at the exit the pressure is 90 Ibf/in.? The pump requires 1/35 hp of power input. Water can be modeled as an incompressible substance with constant density of 60.58 Ib/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

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.?, and 180°F, respectively; at the exit the pressure is 90 Ibf/in.?
The pump requires 1/35 hp of power input. Water can be modeled as an incompressible substance with constant density of 60.58
Ib/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.
