Question
As shown in the figure, an inclined manometer is used to measure the pressure of the gas within the reservoir. The manometer fluid is
mercury, which has a density of 845 Ib/ft3. The manometer fluid rises a distance d = 12 inches along the manometer tube, which is
inclined e = 20° from the horizontal. The atmospheric pressure is 14.7 Ibf/in? and the acceleration of gravity is 32.2 ft/s?.
Patm = 14.7 Ibf/in.?
Gas reservoir
g = 32.2 ft/s?
a
20 in.
Mercury (p = 845 Ib/ft³)
Determine the gas pressure, in Ibf/in?.
Express the pressure as a gage or a vacuum pressure, as appropriate, in Ibf/in2.
