Mode of heat transfer in which the fluid moves under the influence of changes in fluid pressure produced by external work is called
A)Radiation
B)Natural convection
C)Forced convection
D)Conduction

Question

Quizplus · Accepted Answer

Forced convection occurs when fluid movement is caused by external means such as a pump or a fan, which creates a pressure difference that drives the fluid flow, enhancing the heat transfer process. This is different from natural convection, where fluid motion is due to buoyancy forces that arise from density differences caused by temperature variations within the fluid.
