I need help with Fluid Statics?
April 27th, 2010
Daniel asked:
If a person at an altitude of 15,000 ft takes in the same volume of air with each breath as she does while walking at sea level, what is the ratio of the mass of oxygen inhaled for each breath at this high altitude compered to that at sea level?
If a person at an altitude of 15,000 ft takes in the same volume of air with each breath as she does while walking at sea level, what is the ratio of the mass of oxygen inhaled for each breath at this high altitude compered to that at sea level?
please help?

the ratio of the mass of oxygen at increased altitudes should be directly proportional to the atmospheric pressure at that altitude and the atmospheric pressure at sea level.
At sea level the atmospheric pressure = 29.92 in. Hg
At 15,000 ft the atmospheric pressure = 16.89 in. Hg
Ratio = 16.89 in Hg/29.92 in Hg = 0.5645
