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 2008C. Steam enters inlet 3 with flow rate of 1.2 kg/s at 958C. 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 8C.
BIOB34 - Animal Physiology Lecture 4 ***TERM TEST ON OCTOBER 6 *** TH Recap: - When looking at the strict definition of Basal or Standard Metabolic Rate, animals do NOT do anything (eat, moving, reproducing, etc.). Therefore, why do they need any energy What processes are consuming energy under the standard conditions … Refer to chart in Lecture 3 Notes - Protein Synthesis – a system that rebuilds proteins that are wearing out. - Na+-K+-ATPase – Since the membrane cells are not perfectly impermeable to ions, therefore, ions like Na+ and K+ leak across the cell membrane, and since it is important for the ion concentrations to not change, the Na+-K+-ATPase’s function is to pump the ions back into their respective membrane as they leave.
