Question:
For an apparent reason, Maggie, the curious learner, is interested in the human breathing problem this year, and she spent a big portion of a lovely Sunday afternoon learning that topic. What she found is the following.
- An average human being inhales/exhales about 6 L/min of air. Here, the volume of air refers to a measurement condition at 273 K under one atmosphere.
- The inhaled air is a gas mixture of about 80% nitrogen and 20% oxygen. The exhaled air has about 80% nitrogen, 4% CO2 and 16% oxygen.
- The molar mass of CO2 is 44.01 g/mol.
Questions:
a) What is the average inhale/exhale air mass flow rate in/out of your nostrils in kg/sec?
b) What is the average inhale/exhale air molar flow rate in/out of your nostrils in mol/sec?
