Hydrogen is mixed with oxygen in an adiabatic mixing chamber at 100 kPa, 25 ∘C. The flow rate of hydrogen is 4 kmol/s and that of oxygen is 1 kmol/s. The mixture leaves the chamber at 100 kPa. Assume no chemical reaction and use the PG mixture model. Part A Determine the temperature at the exit (T2). Express your answer to three significant figures. Part B Determine the rate of entropy generation (S˙gen) in the device. Express your answer to four significant figures in kW/K.
