A defective seal in the condenser housing resulted in 8 kg/h air leakage during operation. The condenser load is 4600 kg/h of steam with dryness fraction 0.93 and temperature 40C. An air extraction pump was employed to extract the leaked air. Determine the amount of vapour carried away with the air for condensate temperature (air extraction temperature) of 36C. [6] Explain what would happen with respect to the amount of vapour carried away with the air if the condensate temperature is lowered. Discuss from an engineering perspective, the implications of lowering the extracted air temperature. [4]
