Q.

Which of the following is the correct relation between thermal transmittance and thermal time constant?

A. t = q x u
B. t = k/u
C. t = q/u
D. t = u/q
Answer» C. t = q/u
Explanation: thermal transmittance and thermal time constant are related by the equation t = q/u. here, t denotes the thermal time constant, u is the thermal transmittance and q is the quantity of heat stored.
