The mean sea-level pressure (MSLP) is the atmospheric pressure at mean sea level. This is the atmospheric pressure normally given in weather reports on radio, television, and newspapers or on the Internet . The altimeter setting in aviation is an atmospheric pressure adjustment.

4 kwi 2020 · In this equation, p ( h) is the atmospheric pressure at altitude h, p0 is the atmospheric pressure at sea level, g is the gravitational acceleration, ρ0 is the mass density of air at sea level, R is the gas constant, T is the temperature, M is the (average) molar mass, m is the average mass of a gas molecule, and H is a composite parameter somet...
5 gru 2020 · Scientists calculate the atmospheric pressure at sea level by measuring the height of a column of mercury and calculating the pressure the atmosphere has to exert to raise the column to that height.
At sea level, a mercury column will rise a distance of \(760 \: \text{mm}\). This atmospheric pressure is reported as \(760 \: \text{mm} \: \ce{Hg}\) (millimeters of mercury). At higher altitudes, the atmospheric pressure is decreased and so the column of mercury will not rise as high.
Atmospheric properties. At SSL some atmospheric properties are: [2] Pressure, P = 101.325 kPa ⇔ 2116.2 lb f / ft 2 ⇔ 14.696 lb f / in 2 ⇔ 760 mmHg ⇔ 29.92 inHg. Density, = 1.225 kg/m 3 ⇔ 0.002377 slug /ft 3. Temperature, T = 15 °C ⇔ 59 °F ⇔ 288.15 K ⇔ 518.67 °R. Gas constant of air, Rair = 287.057 J/ (kg·K) ⇔ 1716.59 ft·lb/sl·°R) Specific Weight,
The global mean pressure at the surface of the Earth is PS = 984 hPa, slightly less than the mean sea-level pressure because of the elevation of land. We deduce the total mass of the atmosphere ma: (2.2) where R = 6400 km is the radius of the Earth. The total number of moles of air in the atmosphere is Na = ma/Ma = 1.8x10 20 moles. Exercise 2-1.
