A1.0kw heater s constructed of a glass plate with an electrically conducting film which produces a constant heat flux. the plate is 60cm x 60cm and is placed in an airstream at 27°c, 1.0 atm. and u.. 5m/s. calculate the average temperature difference along the plate and the temperature difference at the trailing edge.

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.
