Question
The gage pressure of air in a pressurized water tank is measured simultaneously by both a pressure
gage and a manometer. The differential height h of the mercury column is to be determined.
Assumptions The air pressure in the tank is uniform (i.e., its variation with elevation is negligible due
to its low density), and thus the pressure at the air-water interface is the same as the indicated gage
pressure.
