A 10,000 kW turbo generator operating at rated capacity receives 52,000 kg/h of steam at 2.90MPa and 310°C, exhaust is at 0.007 MPa. At 1.20 MPa and 230°C, there are actually extracted 20% of throttle flow for regenerative heating of feedwater. The generator efficiency is 95%. For an ideal and engine, find (a) the quantity of steam extracted, kg/h (b) W and (c) e. For the actual engine, find (d) the temperature of feedwater from the open heater (e) nk and (f) the approximate enthalpy of exhaust steam and its quality.

Question
A 10,000 kW turbo generator operating at rated capacity receives 52,000 kg/h of steam
at 2.90MPa and 310°C, exhaust is at 0.007 MPa. At 1.20 MPa and 230°C, there are
actually extracted 20% of throttle flow for regenerative heating of feedwater. The
generator efficiency is 95%. For an ideal and engine, find (a) the quantity of steam
extracted, kg/h (b) W and (c) e. For the actual engine, find (d) the temperature of
feedwater from the open heater (e) nk and (f) the approximate enthalpy of exhaust steam
and its quality.
