Mode of heat transfer in which the fluid moves under the influence of changes in fluid pressure produced by external work is called_______________?
Correct answer: C. Forced convection
- A. Radiation
- B. Natural convection
- C. Forced convection
- D. Conduction
Explanation
Forced convection occurs when fluid motion is produced by an external device or pressure change, such as a pump, fan, or compressor. Natural convection instead results from buoyancy caused by density differences.
