Atmospheric pressure, sometimes also called barometric pressure

It is the pressure exerted by the weight of air in the atmosphere of Earth.

Much of the time environmental weight is nearly approximated by the hydrostatic weight created by the heaviness of air over the estimation point.

Low-weight regions have less air mass over their area, while high-weight ranges have more environmental mass over their area.

Similarly, as height increments, there is less overlying climatic mass, so that barometrical weight diminishes with expanding rise.

All things considered, a segment of air one square centimeter [cm2] (0.16 sq in) in cross-segment, measured from ocean level to the highest point of the climate, has a mass of around 1.03 kilograms (2.3 lb) and weight of around 10.1 newtons (2.3 lbf).

That drive (crosswise over one square centimeter) is a weight of 10.1 N/cm2 or 101,000 N/m2.

A segment 1 square crawl (6.5 cm2) in cross-area would have a weight of around 14.7 lb (6.7 kg) or around 65.4 N.

The severity of a tropical storm is related to the depressed atmospheric pressure at its center. Shown below is a photograph of Typhoon Odessa taken from the space shuttle Discovery in August 1985, when the maximum winds of the storm were about 90 mi/hr and the pressure was 40.0 mbar lower at the center than normal atmospheric pressure. In contrast, the central pressure of Hurricane Andrew was 90.0 mbar lower than its surroundings when it hit south Florida with winds...

In a supermarket, air at atmospheric pressure and 25 °C is supplied to an air handling unit through a rectangular duct with a cross section of 0.5 m x 0.1 m. The air handling unit will distribute 2/3 of the air to the large shopping area of the supermarket at 25 °C, and it will cool the remaining air to -5 °C and distribute it to a walk-in refrigerator. To avoid frictional pressure losses, the average air velocity in the...
