A pressurized feed water in a steam power plant is to be heated in an ideal open feedwater heater that operates at a pressure of 2.5497 MPa with the steam extracted from the turbine. If the enthalpy of the feedwater is 254 kJ/kg, the mass fraction of (in percentage) steam extracted from the turbine will be ______.
The enthalpy of the steam entering the feedwater = 3250 kJ/kg. Also, at 2.5497 MPa, hf = 966.7 kJ/kg (Neglect the pump work)Enter numerical value using the virtual keypad. Round off where necessary.
