pressure pressure, in mechanics, ratio of the force acting on a surface to the area of the surface; it is thus distinct from the total force acting on a surface. A force can be applied to and sustained by a single point on a solid. However, a force can only be sustained by the sur...

Air pressure decreases quickly with altitude, reaching one half of its sea-level value at about 18,000 ft (5,500 m). Layers of the Earth's AtmosphereThe earth's atmosphere is composed of distinct layers. The troposphere extends upward from the earth to a height of about 5 mi (8.1 km)...
What is the pressure in atmospheres exerted by a column of water that is 12.5 m high (density of water = 0.987 g/cm^3; gravitational constant = 9.80665 m/s^2, 1 atm = 101,325 Pa = 760 torr = 760 mmHg)? Calculate the pressure in atmospheres in the ocean at a depth of 3.20 km...
A barometer in my lab says that the pressure is 1520.0 mmHg. What is the pressure expressed in atmospheres? The barometric pressure in a cavern was measured to be 28.2 inches of Hg. Convert this pressure to: a) SI unit of pressur...
The pressure exerted on the human body increases by 1 atmosphere for every 10 meters of depth in seawater, so that at 30 meters in seawater a diver is exposed to a pressure of about 4 atmospheres. The pressure of the gases being breathed must equal the external pressure applied to the ...
Pressure in the Body Next to taking a person’s temperature and weight, measuring blood pressure is the most common of all medical examinations. Control of high blood pressure is largely responsible for the significant decreases in heart attack and stroke fatalities achieved in the last three ...
What is the relation between pressure in atmospheres and pressure in pascals ? View Solution Starting with an initial pressure of 5 atm of azoisopropane, 40% of it decomposes into nitrogen and hexane vapours in one hour. The pressure in atm exerted by the mixture in atm at this time will...
(e.g., pressure and temperature, pressure and volume) that hold for anidealgas—a hypothetical construct that real gases approximate under certain conditions. Eventually, these individual laws were combined into a single equation—theideal gas law—that relates gas quantities f...
On the other hand, pressure is measured in units like Pascals (Pa), signifying the intensity of the force distributed over an area. 9 While strain is specifically related to the materials' response and is used in mechanical and civil engineering to assess structural integrity, pressure is a ...
