Question:-
Consider the following statements:
The effect of fouling in a water-cooled steam condenser is that it
1. Reduces the heat transfer coefficient of water
2. Reduces the overall heat coefficient
3. Reduces the area available for heat transfer
4. Increase the pressure drop of water
Of these statements
Option (A)
1, 2 and 4 are correct
Option (B)
2, 3 and 4 are correct
Option(C)
2 and 4 are correct
Option(D)
1 and 3 are correct
Correct Option:
(B)
Question Solution:
The pipe surface gets coated with deposited impurities and scale gets formed due the chemical reaction between pipe material and the fluids. This coating has very low thermal conductivity and hence result in high thermal resistance. Pressure will be affected
