Three return steam lines in a chemical processing plant enter a collection tank operating at steady state at 1 bar. Steam enters inlet 1 with flow rate of 0.8 kg's and quality of 0.9. Steam enters inlet 2 with flow rate of 2 kg's at 200 °C. Steam enters inlet 3 with flow rate of 1.2 kg's at 95 °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) The mass flow rate (in kg/s).

(b) The temperature (in °C).
