A barometer can measure atmospheric pressure using the variation of pressure with depth of a fluid....
2. A barometer reads the atmospheric pressure 764.7 torr. A sample of gas is placed attached to an open-end mercury monometer. The level of mercury in the op arm of the monometer has a height of 136.4 mm, and that in the arm that is in cont with the gas has a height 103.8 mm. What is the pressure of gas in atmosphere?
2. The basic barometer can be used to measure the height of a building. If the barometric readings at the top and at the bottom of a building are 675 and 695 mmHg, respec- tively, determine the height of the building. Take the densi- ties of air and mercury to be 1.18 kg/m2 and 13,600 kg/mÂș, respectively. 3. Freshwater and seawater flowing in parallel horizon- tal pipelines are connected to each other by a double U-tube manometer, as shown in...
A U-tube manometer is used to measure the pressure drop of water (density=1000Kg/m3) in a pipe line, which is in excess of atmospheric pressure. The right limb of the manometer contains mercury (specific gravity=13.6) and is opened to atmosphere. The contact between water and mercury is in left limb. Determine the pressure of water in the main line, if the difference in level of mercury in the limb of U-tube is 10Cm and the free surface of mercury is in...
Measurement of Pressure. An open U-tube manometer similar to Fig. 2.2-4a is being used to measure the absolute pressure p, in a vessel containing air The pressure pb is atmospheric pressure, which is 754 mm Hg. The liquid in the manometer is water having a density of 1000 kg/m. Assume that the densityp is 1.30 kg/m and that the distance Z is very small. The reading R is 0.415 m. Calculate p, in psia and kPa. pb fluid B PB...
EXAMPLE 6-2 Using a Manometer to Measure Gas Pressure When the manometer in Figure 6-5(c) is filled with liquid mercury (d = 13.6 g/cm"), the barometric pressure is 748.2 mmHg, and the difference in mercury levels is 8.6 mmHg. What is the gas pressure Pgas? Analyze We must first establish which is greater: the barometric pressure or the gas pressure. In Figure 6-5(c), the baro- metric pressure forces liquid mercury down the tube toward the gas sample. The barometric pressure...
