C)Convection
D)None of these

Question

Quizplus · Accepted Answer

In the laminar sub-layer of a fluid flowing through a pipe, the fluid velocity is low, and the flow is smooth and orderly. This means that the primary mode of heat transfer in this region is through conduction, where heat is transferred due to the temperature gradient within the fluid, without any significant fluid motion contributing to the transfer.
