Question

What factors or parameters in the fin dictates its efficiency. If you want to improve fin efficiency, clearly describe how you will achieve it.

Answer 1

Step-by-step explanation:

Fin efficiency can be define as the ratio of actual flow of to the maximum flow of heat through fins.

So in short form we can say that

`\eta _(f)=(q_(actual))/(q_(max))`

Lets take infinite long fin to understand the all factors which affect the fin efficiency

So efficiency of long fin given as

`\eta _(fL)=(1)/(mL)`

And we know that

`m = \sqrt{(hP)/(KA)}`

So from we can say that for better efficiency the heat transfer coefficient will be low and conductivity for fin should be high.
