Consider a 4.45-m × 4.45-m × 4.45-m cubical furnace whose floor and ceiling are black and whose side surfaces are reradiating. the floor and the ceiling of the furnace are maintained at temperatures of 547 k and 1100 k, respectively. determine the net rate of radiation heat transfer between the floor and the ceiling of the furnace. (given: the view factor from the ceiling to the floor of the furnace f12 = 0.2, σ = 5.67 × 10-8.)

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.
