Coefficient of thermal conductivity K is...

Coefficient of thermal conductivity K is given by :

A

`(Q.t)/(A(T_(1)-T_(2))d)`

B

`(Q.d)/(A(T_(1)-T_(2))t)`

C

`(A(T_(1)-T_(2))d)/(Q.t)`

D

`(A(T_(1)-T_(2))t)/(Q.d)`

Text Solution

Verified by Experts

The correct Answer is:
B
`Q("k A(T_(1)-T_(2))t)/(d)rArrk=(Qd)/(A(T_(1)-T_(2))t)`
Thus correct choice is (b).
