Q:

Two metallic plate of equal thickness and coefficient thermal conductivity K1 and K2 put together face to face. A common plate is constructed. What is equivalent K?

A) K1k2/k1+k2	B) 2k1k2/k1+k2
C) K1+k2/k1k2	D) None

Answer & Explanation Answer: B) 2k1k2/k1+k2

Explanation:

We know that,

The equivalent K = $\frac{L 1 + L 2}{\frac{L 1}{K 1} + \frac{L 2}{K 2}}$

where L1 & L2 are plate1 & Plate2 thicknesses, K1 & K2 are coefficient thermal conductivity of plate1 & Plate2 respectively.

But here L1 = L2 = L (say)

Then K = L+L/(L/K1 + L/K2) = $\frac{2 K 1 K 2}{K 1 + K 2}$
