WebINTRODUCTION. In chromatography, flow rates should be standardized for columns of different dimensions by expressing the flow rate as linear flow velocity (cm/h). This is defined as the volumetric flow rate (cm 3 /h) per unit cross-sectional area (cm 2) of a given column. However, flow rates are usually measured as volumetric flow rates (mL/min). WebFlow rate Q is defined to be the volume of fluid passing by some location through an area during a period of time, as seen in Figure 12.2. In symbols, this can be written as. Q = V t, 12.1. where V is the volume and t is the elapsed time. The SI unit for flow rate is m 3 /s, but a number of other units for Q are in common use. WebFeb 20, 2024 · Flow rate and velocity are related, but quite different, physical quantities. To make the distinction clear, think about the flow rate of a river.
