A feed water heater in a power plant has two inflows: 0.5 kg/s steam at 320°C and 7 bar and 4.5 kg/s liquid water at 35°C and 7 bar. A single flow exits the feed water heater. Assuming no heat transfer with the surroundings and constant pressure for all flows. Find the outlet temperature, the rate of entropy production in the feed water heater, and locate the three principle states on a sketch of the T-s diagram.
