Pressure-gradient force — The pressure gradient force is not actually a force but the acceleration of air due to pressure difference (a force per unit mass). It is usually responsible for accelerating a parcel of air from a high atmospheric pressure region to a low… … Wikipedia
Pressure coefficient — The pressure coefficient is a dimensionless number which describes the relative pressures throughout a flow field in fluid dynamics. The pressure coefficient is used in aerodynamics and hydrodynamics. Every point in a fluid flow field has its own … Wikipedia
Pressure vessel — Vertical pressure vessels installed in a structure A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. The pressure differential is dangerous and many fatal… … Wikipedia
Pressure gradient — In atmospheric sciences (meteorology, climatology and related fields), the pressure gradient (typically of air, more generally of any fluid) is a physical quantity that describes in which direction and at what rate the pressure changes the most… … Wikipedia
Pressure altitude — In aviation, pressure altitude is the indicated altitude when an altimeter is set to an agreed baseline pressure setting. This setting 101,325 Pa, equivalent to 1013.25 millibar (or hectopascals), or 29.92 inches Hg is equivalent to the air… … Wikipedia
Pressure measurement — The construction of a bourdon tube gauge, construction elements are made of brass Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges. A… … Wikipedia
