A feedwater heater has 5 kg/s water at 5 MPa and 40°C flowing through it, being heated from two sources, as shown in Fig. 8.6. One source adds 900 kW from a 100°C reservoir, and the other source transfers heat from a 200°Creservoir such that thewater exit condition is 5 MPa, 180°C. Find the reversible work and the irreversibility.
