Definition
flow rate whose magnitude is expressed relative to a specified reference quantity
Explanatory Notes
The reference quantity used for normalization may be, for example, membrane area, working volume, or cell amount. The resulting normalized flow rate may therefore have different units depending on the reference quantity. Normalization in this sense does not refer to conversion of a gas flow rate to standard or normal temperature and pressure conditions.
Examples
- permeate flow rate normalized to membrane area during ultrafiltration, expressed as L m⁻² h⁻¹; a perfusion culture operated at 1 VVD, meaning one working volume of medium is exchanged over one day;
Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
There are insufficient constructs to create necessary and sufficient conditions.
Formal Axioms
First-Order Logic Axioms
NormalizedFlowRate(x) → FlowRate(x)
Semi-Formal Natural Language Axioms
if x is a ‘normalized flow rate’ then x is a ‘flow rate’
