Evangelista Torricelli (1608-1647) was the first to put forward the idea that we live at the bottom of an ocean of air. Given the value of atmospheric pressure at the surface of the Earth, and the fact that there is zero pressure in the vacuum of space, determine the depth of the atmosphere, assuming that the density of air and the acceleration of gravity are constant.

- What is the height of a column of liquid in a barometer if the density of the liquid is 0.6460 g/mL and the local atmospheric pressure is 0.8100 bar? Note that the gravitational force on the liquid column divided by the cross sectional area of the column must be equal to the atmospheric pressure.A liquid of density Ꝭ = 850 kg/m3 moves from a horizontal tube of radius r1 into a second horizontal tube of radius r2 (you can consider both tubes to be at the same height). The radius of the second tube is half of the radius of the first tube. The difference in pressure between the two tubes (P1 – P2) is equal to 6.00 x 103 N/m2. Find the speed of the liquid (v1) in the first tube?Suppose a distant world with surface gravity of 7.28 m/s has an atmospheric pressure of 8.28 x 10 Pa at the surface.

(b) What is the weight of a 10.0-m deep cylindrical column of methane with radius 2.00 m? Note: The density of liquid methane is 415 ka/m.

(b) At this depth, what is the buoyant force on a spherical submarine having a diameter of 5.30 m?suppose that a mercury barometer is taken to the summit of mt. everest, where the atmospheric pressure is exactly 1/3 that at sea level. if the mercury has a density of 13500 kg/m^3, what will be the difference in the mercury height in the clossed end and open end of the barometer?Humans evolved in Earth's atmosphere, therefore the pressures interior to the body are relatively close to atmospheric pressure. Because the differences between internal body pressures and atmospheric pressure are so small, individuals have a difficult time gauging the magnitude of atmospheric pressure. Suppose an individual is lying on his stomach with sheets of paper stacked on his back. If each sheet of paper has a mass of 0.00360 kg and is the standard letter size of 8.5 in by 11 in (0.216 m by 0.279 m), how many sheets must be stacked to produce a pressure on his back equal to atmospheric pressure (roughly 101325 Pa)? sheets of paper required:
- In 1656, the Burgmeister (mayor) of the town of Magdeburg, Germany, Otto Von Guericke, carried out a dramatic demonstration of the effect resulting from evacuating air from a container. It is the basis for this problem. Two steel hemispheres of radius 0.350 m (1.15 feet) with a rubber seal in between are placed Fogetner and air pumped out so that the pressure inside is 11.00 millibar. The atmospheric pressure outside is 970 millibar. Calculate the force required'to pull the two hemispheres apart. [Note: 1 millibar=100 N/m2. One atmosphere is 1013 millibar = 1.013×105 N/m² ] Submit Answer Tries 0/12 Two equal teams of horses, are attached to the hemispheres to pull it apart.
