The temperatures on the two sides of a plane wall are t1 and t2 and thermal conductivity of the wall material is prescribed by the relationK = k0 e^(-x/δ)Where, k0 is constant and δ is the wall thickness. Find the relation for temperature distribution in the wall? |
A. | t 1 – t x / t 1 – t 2 = x |
B. | t 1 – t x / t 1 – t 2 = δ |
C. | t 1 – t x / t 1 – t 2 = δ/x |
D. | t 1 – t x / t 1 – t 2 = x/δ |
