A manometer is used to measure the pressure of a
gas in a tank. The fluid used has a specific gravity of
0.85, and the manometer column height is 55 cm, as
shown in Fig. 1-56. If the local atmospheric pressure
is 96 kPa, determine the absolute pressure within the
tank.
A water pipe is connected to a double-U manometer as shown in Fig. P1–109E at a location where the local atmospheric pressure is 14.2 psia. Determine the absolute pressure at the center of the pipe.
1-53 The water in a tank is pressurized by air, and the pres-
sure is measured by a multifluid manometer as shown in
Fig. Pl-53. Determine the gage pressure of air in the tank if
h = 0.2 m, hy = 0.3 m, and h, = 0.46 m. Take the densities
of water, oil, and mercury to be 1000 kg/m', 850 kg/m, and
13,600 kg/m', respectively.
