Problem 2 - Energy Transfer by Heat (10 pts)a. A 15 -cm-thick firebrick has thermal conductivity kb of 0.75Wm*K. At steady state, atemperature difference of 250°C occurs across the firebrick. What is the rate of conductionheat transfer through the firebrick, in kW per m2 of surface area?b.
The rate of conduction heat transfer through a plane wall of dimensions H, W, and L, thermal conductivity k, and temperatures Ti and T2 on the faces can be determined as W T H L (T2 - T6) q = - LK HW q = - Hk (T2 – T1) L (T2 - T6) = - HWK- L q= HWk(T2 - T6).

Question: On the outside of a wall whose thermal conductivity is k, the emissivity is e and convective heat transfer coefficient is h. Taking the positive x direction to be towards the outside and with the air temperature T, an d incident solar radiation flux q, the correct boundary condition, for conduction heat transfer, at this wall surface is
CHAPTER 4. CONDUCTION HEAT TRANSFER: STEADY ST 4.9 Problems 4.1 Reduction of Heat Loss Using a Stagnant Air Film Compare the heat loss in W from two windows of a room, one having a single sheet of glass 10 mm thick while the other has two sheets of glass, 5 mm each, separated by 5 mm of air. The second window is called a thermopane.
