Liquid water (state 1) and steam (state 2) are mixed in a steady flow open feedwater heater and the mixture leaves at state 3. The flow rate at state 1 is 0.7 kg/s, the pressure is p1 = 1 bar, and the temperature is T1 = 40 C. The pressure at state 2 is p2 = 1 bar and the temperature is T2 = 400 C. The mixture leaves at p3 = 1 bar with quality x3 = 0.25. heat transfer from the feedwater heater is at a rate of 100 kW and leaves at an average boundary temperature of 50 C. then environmental conditions are T0 = 25 C and p0 = 1 bar.Determine the mass flow rate at state 2.
