Reserve Problem 4.006 Tutorial SI

A feedwater heater in a vapor power plant operates at steady state with liquid water entering at inlet 1 with 45°C and 5.0 bar. Water vapor at 320°C and 5.0 bar enters at inlet 2. Saturated liquid water exits with a pressure of 5.0 bar. Ignore heat transfer with the surroundings and all kinetic and potential energy effects. The mass flow rate of the liquid entering at inlet 1 is 3.2 × 105 kg/h. Determine the temperature at the exit, , in °C, and the mass flow rate at inlet 2, in kg/h.
