Question 4. In a regenerative steam cycle employing three closed feedwater heaters, the steam is supplied to the turbine at 42 bar and 500 °C and is exhausted to the condenser at 0.035 bar. The bleed steam for feed heating is taken at pressures of 15, 4 and 0.5 bar. Assuming ideal processes and neglecting pump work, calculate: (a) The fraction of the boiler steam bled at each stage (b) The power output of the plant per unit mass flow rate of boiler steam. (c) The cycle efficiency. And (d) The specific steam consumption
