ercise 66.1 A surface condenser is fitted with separate air and condensateoutlets. A portion of the cooling surface is screened from theincoming steam and the air is passes over these screened tubes tothe air extraction and becomes cooled below the condensatetemperature. The condenser receives 20 000kg/hr of dry saturatedsteam at 36.2°C. At the condensate outlet the temperature is 34.6°C TKand at the air extraction the temperature is 29°C. The volume of airand vapour leaving the condenser is 3.8m3/min. Assume constantpressure throughout the condenser, calculate:6.1.1 the mass of air removed per 10 000kg of steam (2.63kg);6.1.2 the mass of steam condensed in the air cooler perminute (0.5kg/min)%3B6.1.3 the heat rejected to the cooling water (13451kW).
