In case when both the surfaces of plane wall are at different temperature, we get an expression i.e.T MAX – T W2 /T W1 – TW2 = (B + 1)²/4BWhat is the value of B?

A. (q g) (δ)²/2k (T W1 – TW2)
B. (q g) (δ)³/3k (T W1 – TW2)
C. (q g) (δ)⁴/4k (T W1 – TW2)
D. (q g) (δ)⁵/5k (T W1 – TW2)
Answer» B. (q g) (δ)³/3k (T W1 – TW2)
