Direct subclasses:

• partial pressure

Definition

relational quality of a material entity that is the amount of normal force exerted by that material entity per unit area across a surface, boundary, or interface

Examples

• the pressure of compressed air against the inner surface of a supply line; the pressure of gas in a bioreactor headspace; the pressure of liquid at the inlet of a chromatography column; the pressure of steam in an autoclave chamber

Primitive Class

This class is declared primitive and it does not have necessary and sufficient condiftions defined.

Primitive Rationale

There are insufficient constructs for creating a set of necessary and sufficient conditions

Formal Axioms

First-Order Logic Axioms

Pressure(x) → RelationalQuality(x) ∧ ∃m (MaterialEntity(m) ∧ qualityOf(x, m))

Semi-Formal Natural Language Axioms

if x is a ‘pressure’ then x is a ‘relational quality’ that is the ‘quality of’ some ‘material entity’
