For a fluid flowing in an annulus space, the wetted perimeter for heat transfer and pressure drop are
A)Same
B)Different
C)Never different
D)Linearly related

Question

Quizplus · Accepted Answer

The wetted perimeter for heat transfer and pressure drop in an annulus space are different because the considerations for heat transfer often involve both the inner and outer surfaces, while pressure drop calculations typically focus on the flow characteristics and friction along the surfaces in contact with the fluid.

For a Fluid Flowing in an Annulus Space, the Wetted
