Pressure what is 1 bar

So there are two possible answers:. If you are looking to convert pressure to force you will need to know the effective area on which the force is acting:. What is 1 bar expressed in metres e. Skip to primary navigation Skip to main content Skip to primary sidebar The bar is a widely used metric unit of measurement for pressure and 1 bar equals precisely , pascals.

In general, pressure or the force exerted per unit area on the boundaries of a substance is caused by the collisions of the molecules of the substance with the boundaries of the system. As molecules hit the walls, they exert forces that try to push the walls outward. The forces resulting from all of these collisions cause the pressure exerted by a system on its surroundings. Pressure as an intensive variable is constant in a closed system.

It really is only relevant in liquid or gaseous systems. The bar is a metric unit of pressure. The bar is commonly used in the industry and in the meteorology , and an instrument used in meteorology to measure atmospheric pressure is called barometer. Atmospheric pressure is often given in millibars where standard sea level pressure is defined as mbar, 1. See also: Pascal — Unit of Pressure. See also: Pound per square inch — psi.

See also: Typical Pressures in Engineering. Pressure as discussed above is called absolute pressure. Often it will be important to distinguish between absolute pressure and gauge pressure. The bar is still widely used in descriptions of pressure because it is about the same as atmospheric pressure.
