The two ends of a rod of length L and a uniform crosssectional area A are kept at two temperatures T_ 1 and T _ 2 ( ~T _ 1 T _ 2 ). The rate of heat transfer, dQ dt through the rod in a steady state is given by:

Question

The two ends of a rod of length L and a uniform crosssectional area A are kept at two temperatures T_ 1 and T _ 2 ( ~T _ 1 > T _ 2 ). The rate of heat transfer, dQ dt through the rod in a steady state is given by:

Quantrex Academy · Accepted Answer

Correct answer: C. k A (T_ 1 -T_ 2 ) L

dQ dt = kA ( T _ 1 - T _ 2 ) L [ ( T _ 1 - T _ 2 ) . is the temperature difference ]
