The standard liter per minute (SLM or SLPM) is a unit of (molar or) mass flow rate of a gas at standard conditions for temperature and pressure (STP), which is most commonly practiced in the United States, whereas European practice revolves around the normal litre per minute (NLPM). [1]
Standard cubic centimeters per minute (SCCM) is a unit used to quantify the flow rate of a fluid. 1 SCCM is identical to 1 cm³ STP /min. Another expression of it would be Nml/min.
Cubic metre per second or cubic meter per second in American English (symbol m 3 ⋅ s −1 or m 3 /s) is the unit of volumetric flow rate in the International System of Units (SI). It corresponds to the exchange or movement of the volume of a cube with sides of one metre (39.37 in) in length (a cubic meter , originally a stere ) each second .

Volumetric flow rate should not be confused with volumetric flux, as defined by Darcy's law and represented by the symbol q, with units of m 3 /(m 2 ·s), that is, m·s −1. The integration of a flux over an area gives the volumetric flow rate. The SI unit is cubic metres per second (m 3 /s).
is the gross amount of air circulated through the fan (or ventilation system) [m 3 /s] There are various sub-definitions of SFP for different specific applications, including SFP e (building energy performance calculations), SFP v (for performance verification tests), SFP i (individual fan), SFP AHU (air handling unit), SFP FCU (fan coil unit ...
Q - volume flow rate of the phase, m 3 /s; A - cross sectional area, m 2; Using the concept of porosity, the dependence between the advection velocity and the superficial velocity can be expressed as (for one-dimensional flow): = where: is porosity, dimensionless; u is the average fluid velocity (excluding the other phase, solids, etc.), m/s.
