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.?, and 180°F, respectively; at the exit the pressure is 60 Ibf/in.? The pump requires 1/25 hp of power input. Water can be modeled as an incompressible substance with constant density of 60.58 Ib/ft 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 = i °R

A mixing vessel initially contains 3,949.62 lb of liquid fluid. The vessel is fitted with two inlet pipes, one delivering hot fluid at a mass flow rate of 0.876 lb/sec and the other delivering cold fluid at a mass flow rate of 0.557 lb/sec. Fluid exits through a single pipe at a mass flow rate of 1.242 lb/sec. Calculate the amount of fluid, in lb, in the tank after 35 minutes.
