Mechanical Engineering

A pump is used to circulate hot water in a home heating system.Water enters the well-insulated pump operating at steady state at arate of 0.42 gal/min. The inlet pressure and temperature are 14.7lbf/in.2, and 180°F, respectively; at the exit thepressure is 90 lbf/in.2 The pump requires 1/35 hp ofpower input. Water can be modeled as an incompressible substancewith constant density of 60.58 lb/ft3 and constantspecific heat of 1 Btu/lb · °R.


Neglecting kinetic and potential energy effects, determine thetemperature change, in °R, as the water flows through thepump.
