Three return steam lines in a chemical processing plan enter a collection tank operating at a steady state at 1 bar. Steam enters inlet 1 with flow rate of 0.8 kg/s and a quality of 0.9. Steam enters inlet 2 with flow rate of 2kg/s at 200 degrees C. Steam enters inlet 3 with flow rate 1.2 kg/s at 95 degrees C. Steam exits the tank at 1 bar. The rate of heat transfer from the collection tank is 40 kW. Neglecting kinetic and potential energy effects, determine for the steam exiting the tank: (a)Mass flow rate in kg/s (b) the temperature in degrees C.
