Standard air pressure at sea level in mercury

Webb17 dec. 2024 · Sea Level Pressure. The air pressure is adequate to the pressure exerted by a mercury column of height “h”. Atmospheric pressure = h × d × g, where h is the height of the mercury column, d the density of mercury, and g the acceleration due to gravity. Atmospheric Pressure = = 0.76 × 13600 × 9.8 = 101293 Pa.

The standard atmosphere was originally defined as the pressure exerted by 760 mm of mercury at 0 °C (32 °F) and standard gravity (gn = 9.80665 m/s ). It was used as a reference condition for physical and chemical properties, and was implicit in the definition of the Celsius temperature scale, which defined 100 °C (212 °F) as the boiling point of water at this pressure. In 1954, the 10th General Conference on Weights and Measures (CGPM) adopted standard atmosphere for g… Webb10 feb. 2024 · The standard temperature in aviation is measured at the mean sea level (msl) pressure of 29.92 inches of mercury (Hg) and is 15° C or 59° F.
