Answer (Detailed Solution Below)
Detailed Solution

- The performance of condenser gets affected badly by presence of air which will remain non condensable.
- It covers the heat transfer surfaces such as outside the surface of condenser tubes and
reduces the condensing heat transfer coefficient.
- Clinging of air to surface reduces the condensing coefficient
- air imparts large thermal resistance due to its low thermal conductivity
