3. In a nuclear power plant, saturated steam at 30 bar enters a high pressure turbine and expends isentropically to a pressure at which its quality is 0.841. At this pressure, the steam is passed through a moisture separator which removes all the liquid. Saturated vapour leaves the separator and is expanded isentropically to 0.04 bar in low pressure turbine, while the saturated liquid leaving the separator is returned via a feed pump to the boiler. The condensate leaving the condenser at 0.04 bar is also returned to the boiler via a second feed pump (a) Calculate the cycle efficiency and turbine outlet quality taking into account the feed pump term 35.5%, 0.824 and (b) Recalculate the same quantities for a cycle with the same boiler and condenser pressure but 35% 0.716 without moisture separation 1 of 4
