Consider the following statements:The effect of fouling in a water-coo...
Ans. (b) 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 results in high thermal
resistance. Pressure will be affected.

Effect of Fouling in a Water-Cooled Steam Condenser
Fouling is the accumulation of unwanted deposits on the surface of heat transfer equipment. In a water-cooled steam condenser, fouling can have several effects, as mentioned below:
Reduces Heat Transfer Coefficient of Water
The heat transfer coefficient is a measure of how well a fluid can transfer heat from one surface to another. Fouling reduces the heat transfer coefficient of water by forming a layer of unwanted deposits on the heat transfer surface, which acts as an insulator and reduces the rate of heat transfer.
Reduces Overall Heat Transfer Coefficient
The overall heat transfer coefficient is a measure of how well the entire heat transfer system is performing. Fouling reduces the overall heat transfer coefficient by reducing the heat transfer coefficient of water and reducing the area available for heat transfer.
Reduces Area Available for Heat Transfer
Fouling reduces the area available for heat transfer by forming a layer of unwanted deposits on the heat transfer surface, which reduces the effective surface area available for heat transfer.
Increases Pressure Drop of Water
Fouling increases the pressure drop of water by reducing the effective flow area, which increases the resistance to flow and increases the pressure drop.
Correct Option
Option B is correct, as fouling reduces the overall heat transfer coefficient, reduces the area available for heat transfer, and increases the pressure drop of water.
