Definition

saturation ratio of a gas mixture whose magnitude is the partial pressure of water vapor in that gas mixture relative to the saturation vapor pressure of water under the same temperature conditions

Examples

• the relative humidity of incubator air at 37 °C; the relative humidity of cleanroom air during environmental monitoring; the relative humidity of humidified air supplied to a cell culture incubator; the relative humidity of air in a stability chamber; the relative humidity of air in a storage area for moisture-sensitive material

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

RelativeHumidity(x) → SaturationRatio(x) ∧ ∃m∃g(MixedMaterial(m) ∧ qualityOf(x,m) ∧ GaseousAggregateState(g) ∧ hasQuality(m,g))

Semi-Formal Natural Language Axioms

if x is a ‘relative humidity’ then x is a ‘saturation ratio’ that is the ‘quality of’ some ‘mixed material’ that ‘has quality’ some ‘gaseous aggregate state’
