A de-superheater works by injecting liquid water at 20 degrees C into a 10 kg/s stream of superheated water vapor at 300 kPa and 200 degrees C, the existing water is saturated vapor/ This type of device is isobaric. Assume the device is adiabatic and neglect kinetic and potential energy changes: h(tot) = h.
1. What is the mass flow rate of liquid water?
2. What is the existing mass flow rate of saturated vapor?
3. What is the entropy generation rate?
