Problem (8.2) A steam turbine develops 3000kW when the steam is supplied at 10 bar and 250°C. The vacuum in the condenser is maintained at 65 cm of Hg. The barometric reads 75.2 cm of Hg. The rise in temperature of cooling water is limited to 15°C. The temperature of the condensate coming out of condenser is 35°C. Find, (a) specific steam consumption of the plant, and (b) quantity of cooling water circulated through the condenser per hour. Assume there is no leakage in the condenser.

Question
Problem (8.2) A steam turbine develops 3000kW when the steam is supplied
at 10 bar and 250°C. The vacuum in the condenser is maintained at 65 cm of
Hg. The barometric reads 75.2 cm of Hg. The rise in temperature of cooling
water is limited to 15°C. The temperature of the condensate coming out of
condenser is 35°C. Find, (a) specific steam consumption of the plant, and (b)
quantity of cooling water circulated through the condenser per hour. Assume
there is no leakage in the condenser.
Ans.[(a) 4.8 kg/kW.h, (b) 447 tons/h]
