We will be creating a useful logging class. this class can be used as a means of advanced logging in other c++ programs. it will use a factory method design pattern such that debugging can be implemented with different classes but the main body of code will not know which class it is using. it will use a singleton design pattern that will allow us to get a logging object from within whatever function requires logging output.

Apump 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 1/15 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 or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
