engineering recuitment ISRO Scientist Mechanical Mock Test Heat Transfer Convection Boiling and Condensation
In film boiling the heat transfer rate increases with the increasing temperature due to
1. heat transfer taking place between the heated surface and the liquid.
2. a large number of nucleation sites.
3. radiation heat transfer between the vapour film and the liquid
