Interactive atmospheric pressure map. ICON and GFS models. Shows global forecasted mean sea-level pressure.
Air pressure above sea level can be calculated as. p = 101325 (1 - 2.25577 10-5 h) 5.25588 (1) where . 101325 = normal temperature and pressure at sea level (Pa) p = air pressure (Pa) h = altitude above sea level (m) Example - Air pressure at Elevation 10000 m. The air pressure at altitude 10000 m can be calculated as
This is in contrast to mean sea-level pressure, which involves the extrapolation of pressure to sea level for locations above or below sea level. The average pressure at mean sea level in the International Standard Atmosphere is 1,013.25 hPa, or 1 atmosphere (atm), or 29.92 inches of mercury.
19 paź 2023 · An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury. Atmospheric pressure drops as altitude increases.
Online calculator, figures and tables showing density, specific weight and thermal expansion coefficients of air at temperatures ranging -100 to 1600 °C (-140 to 2900 °F) at atmospheric and higher pressure - Imperial and SI Units. Air - Specific Heat vs. Pressure at Constant Temperature.
4 dni temu · To calculate the air pressure at a certain altitude, use this simple formula: P = P0 × exp(-g × M × (h - h0)/(R × T) where: P0 and h0 — The pressure and altitude of the reference point. Often, these values correspond to the ones at sea level. P — The pressure at altitude h. T — The temperature at altitude h.
The average atmospheric pressure at sea level is defined by the International Standard Atmosphere as 101325 pascals (760.00 Torr; 14.6959 psi; 760.00 mmHg). This is sometimes referred to as a unit of standard atmospheres (atm) .
