Steam is then reheated at constant pressure to same (b) temperature. Heat is transferred to the steam in the boiler at a rate of 58,416 kJ/s. And the mass flow rate of steam through the cycle is 20 kg/s. The moisture content of the steam at the exit of the low-pressure turbine is not to exceed 8 per cent. Steam is cooled in the condenser by the cooling water from a nearby river, and the temperature rise is 12°C.
