B) convection.
C) radiation.
D) none of the above.

Question

Quizplus · Accepted Answer

This scenario describes forced convection, which is a type of heat transfer that occurs when a fluid in motion (convection) comes into contact with a solid surface (such as a pipe, for example) that has a temperature different from the fluid. This is different from conduction, which involves heat transfer through a material or between materials in contact with each other, and radiation, which involves the transfer of heat energy through electromagnetic waves.
