In a steam power station, steam at boiler outlet is at 30 bar and 350°C. The steam is expanded at two points at a pressure of 10 bar and 2 bar and condenser pressure is 0.05 MPa. The enthalpy of steam entering and leaving the condenser is 2230 kJ/kg and 212 kJ/kg respectively. The enthalpy of the steam entering the first and second points are 2815 kJ/kg and 2550 kJ/kg respectively. Also, enthalpy at liquid line at 2 bar and 10 bar is 431 kJ/kg and 676 kJ/kg respectively. Neglect pump work and find mass of steam bled per kg of steam from first and second point. (in kg)
