Question

With the help of fins the heat transfer can be increased by about (a) 4 times (b) 6 times (c) 8 times (d) 10 times

Answer 1

Answer:10

Explanation:

Answer 2

Answer:

The heat transfer can be increased about 10 times using the fins. Hence, the correct option is (d) 10 times.

Explanation:

In heat transfer, fins are extended surfaces from an object to increase the rate of heat transfer to or from the environment by increasing convection.

When the fin is longer, the heat transfer area is larger, and thus the higher the rate of heat transfer from the fin, but due to the larger fin, the mass will be bigger and the price will be high.

When the area of the fin is increased, the heat transfer will be increased.

Hence, the heat transfer can be increased about 10 times using the fins.
