Question

8
Steam at 70 bar and 460°C is supplied to a steam turbine. After expanding to 26 bar in high
pressure stages, it is reheated to 420°C at the constant pressure. Next; it is expanded in
intermediate pressure stages to an appropriate minimum pressure such that part of the steam bled
at this pressure heats the feed water to a temperature of 180°C. The remaining steam expands from
this pressure to a condenser pressure of 0.07 bar in the low pressure stage. The isentropio
efficiency of HP stage is 78.6%, while that of the intermediate and LP stage is 83% each Determine
the minimum pressure at which bleeding is necessary, the quantity of steam bled per kg of flow at
the turbine inlet and the efficiency of the cycle​
