Physics · Heat Transfer
Forced convection heat transfer is primarily characterised by:
- 1the total absence of any temperature gradients within the fluid volume
- 2the natural buoyancy-driven flow of fluid due to density differences
- 3the use of external devices such as fans, blowers, or pumps to force fluid motion✓
- 4heat transfer occurring solely through medium-less radiation
Correct answer
the use of external devices such as fans, blowers, or pumps to force fluid motion
