1- Microwave radiation is incident on one side of a planar wall with a heat conductivity coefficient k. (x-0) 9(W/m²) q(x) = q,(1-) microwave radiation is fixed. leads to volumetric heating. While this surface is kept at a constant temperature To, the other surface at x=L is very well insulated. Determine the temperature distribution T(x) in terms of x, L, k, qo and To.

You are designing a chamber to contain the radiation emitted by nuclear decay during a fusion reaction. The left face of the (plane) chamber wall (x = 0) is exposed to the radiation and the right face of the wall (x = L) is perfectly insulated. To facilitate the fusion reaction, the left face of the wall is maintained at fixed temperature To. The radiation penetrates the wall causing uniform heat generation that varies with location inside the wall as ) = 40 (1 - 1) g(x) where qo [W/m^3 ] is a constant. Determine an expression for the temperature distribution in the wall T(x) assuming the thermal conductivity of the wall (k) is constant.

Question 4-83 is the one I need help with

Two parts and label (A) & (B) Solve carefully! Question : The roof of a car in a parking lot absorbs a solar radiant flux of 600 W/m2, while the underside is perfectly insulated. The convection coefficient between the roof and the ambient air is 15 W/m2.K and the roof’s surface emissivity is 0.5. If the ambient air temperature is 25C, answer the following questions: PART (A) Neglecting radiation heat transfer, find the temperature of the roof under steady state conditions. Part ( B) Neglecting convective heat transfer, find the steady state temperature of the roof [Tsur =0]?
