An inventor has provided the steady-state operating data shown in the figure below. The system produces mechanical power and increases the temperature of a stream of air ( ṁ = 2 kg/s). The system receives and discharges energy by heat transfer at the rates and temperatures indicated on the figure. Q̇1 and Q̇2 are into the system, and Q̇3 is out of the system. Kinetic and potential energy changes of the flowing fluid are negligible. Treating the air as having constant specific heats cV = 0.718 kJ/(kg·K) and cP = 1.005 kJ/(kg·K), determine: The outlet temperature of the air. The rate of entropy generation inside this device as described. Is this device feasible? You must include a schematic with appropriate energy interactions and start from general forms of any relevant governing equations to be eligible for full credit on this question.

If you are asked to perform a test statistic to compare if levels of estrone are significantly different in the control vs diseased group, explain how would you perform that test by answering the following questions; 1. What are your null and alternate hypotheses? 2. What test would you use to test that hypothesis? You will need to run that test to answer the next question.
