b) The steam at 30 bar and 400 °C is supplied to a steam turbine, Two regenerative heaters are used by extracting the steam at 6 bar and 1 bar. The steam exhaust pressure is 0.07 bar. The feeds coming out from first and second heaters are saturated liquids at corresponding pressure. The feed drain from the first heater is passed into the second heater through a steam trap and the combined drains from the second heater are pumped by a drains pump into the feed pipe after the second heater. If the internal power developed by the turbine is 10 MW. Find the quality of steam extracted at each point of the. turbine per minute. Take the isentropic efficiency of each stages of turbine 80%.
