Pressure: Measurement, Definition & Types

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure.

How Pressure connects Entity context

The extracted context around Pressure shows recurring relationship patterns in the source. For example, Pressure → Analysis, Applied, Boyle's, Charles, Combination, Comparison, Component, Device, Equipment, Gay-Lussac's, Great, Kinetic, Line, Local, Relation, Repulsive, Temperature, Term, Theorem, Understanding Another extracted example is Pressure → barye, lower-case p, pascal, physical concept that describes a thermodynamic ensemble of all factors that produce the same volumetric strain in a material, pressure a fluid exerts when it is forced to stop moving, pressure of a vapour in thermodynamic equilibrium with its condensed phases in a closed system, relevant measure of pressure wherever one is interested in the stress on storage vessels and the plumbing components of fluidics systems, same at the bottom of each vase, scalar proportionality constant that relates these two normal vectors, scalar quantity. Use these groups to spot repeated connection types before inspecting the individual relationships.
