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 2 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.
