## Question:

Consider one-dimensional conduction in a plane composite wall. The outer surfaces are exposed to a fluid at 25°C and a convection heat transfer coefficient of 1000 W/m2 ∙ K. The middle wall B experiences uniform heat generation qB, while there is no generation in walls A and C. The temperatures at the interfaces are T1 = 261°C and T2 = 211°C.

(a) Assuming negligible contact resistance at the interfaces determines the volumetric heat generation qB and the thermal conductivity kB.

(b) Plot the temperature distribution, showing its important features.

(c) Consider conditions corresponding to a loss of coolant at the exposed surface of material A (h = 0). Determine T1 and T2 and plot the temperature distribution throughout the system.

Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
