Problem (8.1) The steam at 100 bar and 500°C is supplied to a steam turbine of 30 MW capacity. The vacuum maintained in the condenser is 71 cm of Hg when the barometer reads 76 cm of Hg. The steam coming out of the turbine is condensed in a surface condenser using river water for cooling. The rise in temperature of the cooling water is limited to 10°C. The temperature of the water at the inlet of the condenser is 20°C. The condensate comes out of condenser as saturated liquid. Find (a) the mass of steam supplied to the turbine per hour, (b) Capacity of the pump to circulate water, (c) the heat transfer area of the condenser if the overall heat transfer coefficient is 400 W/M2°C.
