Q:
In a jet condenser, the difference between the temperature of steam (dry and saturated) entering the condenser and the condensate leaving the condenser is 4°C. The amount of cooling water required and the mass of steam being supplied to the condenser are 900000 kg/hr and 12000 kg/hr. Take the latent heat of water to be 2300 kJ/kg and the specific heat at constant pressure to be 4.186 kJ/kgK. If the temperature of cooling water entering the condenser is 26°C, determine the temperature of cooling water leaving the condenser.
A) 35.65°C

B) 33.38°C

C) 45.54°C
 D) 28.32°C
