A barometer is constructed using a closed-end tube
containing a vacuum above a column of mercury. On a certain day,
the pressure exerted solely by this column of mercury at the bottom
of the tube is 1.024 x 10^5 Pa. Which quantity or quantities are
equal to this measurement?
A. neither the absolute pressure at the bottom and the atmospheric
pressure
B. the atmospheric pressure
C. the absolute pressure at the bottom
D. both the absolute pressure at the bottom and the atmospheric
pressure

In a U-tube barometer, some air was left above the mercury in the closed tube. The difference in height between the column of mercury in the closed tube and im the open thbe is 75.6 cm when the atmospheric pressure is 78.9 cm of mercury. Calculate the air pressure in the space above the mercury in a closed tube. Express the presshre in dynes/cm^2

The column of a mercury barometer is calibrated in linear units
(such as inches or millimeters) and thus the air pressure observed
on such a barometer is reported in terms of these linear units.
This measurement of pressure can be converted to other common
pressure units. Some conversion factors are shown here.

12) As shown in fig. an open-tube manometer containing water (p.-10 kg/m') and mercury (p-1.36x 10 kg/m). The height of water in the left column above the interface A is h' - 30 cm, while the height of mercury in the right column above B is h - 20 cm. The right column is open to the atmosphere Patm - 1.01 10 Pa. The pressure P in the container is: a) P-1.25x10 Pa a) P=0.56*10Pa b) P-4.29x109 Pa d) P-2.46x10*...

8. The figure shows a tank within a tank, each containing air. Pressure gage A, which indicates pressure inside tank A, is located inside tank B and reads 5 psig (vacuum). The U-tube Pa 14.7 psia Tank B manometer connected to tank B contains water with a column length of 10 in. Using the data shown on the figure, determine the absolute pressure of the air inside tank B and inside tank A, both in psia. The atmospheric pressure surrounding...

5. An open end manometer constructed from a U-shaped tube was operated using an oil which has a density of 1.088 g ml-1. In a particular measurement, the level in the end connected to the gas manifold, on which the experiment was being conducted, measured 76.2 cm above the U-neck, while the level in the open end (to the atmosphere) was 23.8 cm above the U-neck. The outside air pressure in the laboratory was measured as 754...

A piston with a radius of 2.5 cm is placed into a cylindrical tube a distance of 4.5 cm from the closed end of the tube, holding in a quantity of air. The piston is attached to a spring with a spring constant of 324 N/m. The other end of the spring is attached to a rigid wall. The tube is surrounded in ice water which keeps the gas at a temperature of o°C. Initially, the spring is relaxed, and...
