FLOW RATE CALCULATOR - PRESSURE AND DIAMETER | COPELY
Flow Rate Calculator. With this tool, it is possible to easily calculate the average volumetric flow rate of fluids by changing each of the three variables: length, pressure and bore diameter. The effects on the predicted flow rate are then given in three graphs, where in turn two of the variables are kept constant and the flow rate is plotted ...

MAINTAINING LINEAR VELOCITY (HPLC)
Most HPLC's operate in the pressure range between 30 and 200 bar. Maintaining linear velocity is the single most important factor when trying to reproduce a chromatographic separation on columns of differing diameters. Since flow rate directly impacts HPLC system pressure a discussion of parameters that affect system pressure are listed below.

HOW AN HPLC PUMP WORKS | THERMO FISHER SCIENTIFIC - US
How an HPLC pump works. Most modern HPLC pumps have at least one pair of reciprocating pistons. One piston delivers the flow while the other aspirates the mobile phase at a programmed flow rate. Piston switching in pumps uses either one motor with a cam drive or multiple linear drive motors – one for each piston.
