Definition

flow rate whose magnitude is determined by the mass of material transported across the specified surface or boundary per unit of elapsed time

Examples

• mass flow rate of air supplied to a bioreactor sparger; mass flow rate of carbon dioxide in an exhaust gas stream; mass flow rate of buffer through a chromatography column; mass flow rate of liquid feed through a process line

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
