(a) What are the need of a surface condensing ? Write disadvantages and advantages of Jet condenser and surface condenser.

(b) A surface condenser is designed to handle 10000 Kg of steam/hr. The steam enters at 0.08 bar and 0.9 dny and leaves the condenser
at a corresponding saturation temperature. The pressure is constant throughout the condenser. Determine the cooling water flow rate/hr,
if cooling water temperature rise is limited to 10^oC
