Fins are provided on heat transferring surface in order to increase: Correct Answer Heat transfer area

Explanation:

Heat flow mainly depends on three factors

  • area of the surface
  • temperature difference and
  • the convective heat transfer coefficient.

The rate of heat transfer can be increased by enhancing any one of these factors.

  • Fins are thus used whenever the available surface area is found insufficient to transfer the required quantity of heat with the available temperature gradient and heat transfer coefficient.
  • In the case of fins, the direction of heat transfer by convection is perpendicular to the direction of conduction heat flow.
  • Fins are the extended surface protruding from a surface or body, and they are meant for increasing the heat transfer rate between the surface and the surrounding fluid by increasing the heat transfer area.
