WebMar 27, 2016 · 2. I was wondering how I can calculate the velocity of gas through a pipe. The gas, assuming ideal behavior, in a pipe (cylinder) of volume of 222.4 L has a pressure of 1.95 atmospheres and a density of 2.25 kg/m 3. Knowing that there will be turbulent flow, the equation, V = 2 Δ P ρ ( 4 f Δ x D − 1) can be used. 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).
