Answer 1

Heya _____

Ques ___ Find the method that will dissipate minimum heat ___ ??

Ans ______

Fins are used in a large number of applications to increase the heat transfer from surfaces. Typically, the fin material has a high thermal conductivity. The fin is exposed to a flowing fluid, which cools or heats it, with the high thermal conductivity allowing increased heat being conducted from the wall through the fin. The design of cooling fins is encountered in many situations and we thus examine heat transfer in a fin as a way of defining some criteria for design.

This is geometry of heat transfer...

Thank you

Answer 2

Methods of minimizing heat dissipation involves :

Preventing heat escape by convection :

For this purpose we need to change the material of the object so that the heat will not be able to escape by the process of convection.

Preventing heat escape by radiation

We need to put up a covering surface so that heat cannot escape by radiation.

Infact lowering the temperature of the body can also help .

Preventing heat loss by conduction

We should cover the body with a non conductor of heat or a bad conductor of heat . This will help us to prevent heat loss by conduction.
