1. If the partial pressure of water vapor is 47 mm Hg in the lungs at 760 mm Hg pressure, what percentage of air does the water vapor constitue?
2. What is the gauge pressure exerted by a 50 cm column of water? Use density of H20 = 1 g/cc, and gravity = 10 m/s/s.
3. What pressure in feet of water corresponds to 1/5 Atmospheres?
