a. Decreases the thermal resistance of

b. Decreases the rate of heat transfer the heat transfer

d. Increases the thermal conductivity of the walls       

a. Decreases the thermal resistance of

b. Decreases the rate of heat transfer the heat transfer

c. Protects pipe wall from corrosion

d. Increases the thermal conductivity of the walls       

Explanation / Answer

Fouling will results addition of extra material on the walls of heat exchanger.

This inctincre thermal resistance and decrease the thermal conductivity.

And the fouling products are sometimes corrosion products. They act as catalysts to the corrosion process. So it will not protect from the corrosion.

As fouling increases the thermal resistance, it will decrease the rate of heat transfer.

Answer is B)
