Two air flows are combined to a single flow. One flow is 1 m3/s at 20oC and the other is 2 m3/s at 200oC, both at 100 kPa. They mix without any heat transfer to produce an exit flow at 100 kPa. Neglect kinetic energies and find the exit temperature and volume flow rate.

Following several days at high altitude the body responds to the decreased oxygen content of the atmosphere by increasing the amount of 2,3-bisphosphoglycerate it produces. Based on this information and refering to the graph below, identify the correct response from the options. Y (fraction saturation) 1.0 0.8 0.6 0.4 0.2 0.0 0 20 Oxygen Binding plot 40 60 p02 (torr) 80 100 A) Curve y=high altitude and gives a greater release of oxygen to the tissues B) Curve x = high altitude and gives a greater release of oxygen to the tissues C) Curve y=high altitude and allows more oxygen to be bound at low oxygen levels D) Curve x = high altitude and allows more oxygen to be bound at low levels

The kinetic data in the following table were obtained for the reaction of carbon dioxide and water to produce bicarbonate and hydrogen ion catalyzed by carbonic anhydrase. H2O + CO2--> HCO3 + H+ Carbon Dioxide Concentration (mmol L-') 1.25 2.5 5.0 20.0 1/Velocity (M'sec) 36 x 10³ 20 x 10³ 12 x 10³ 6 x 10³ [H. DeVoe and G. B. Kistiakowsky, J. Am. Chem. Soc. 1961 83 (2), 274-280.] Use Excel (or similar) to generate a Line Weaver-Burke plot, then use the equation for a linear-fitted trend line to calculate the substrate affinity of CO2 for carbonic anhydrase. Answer in units of mM. Enter numerical values only, no letters or symbols. Round answer to 2 significant figures.
