WebGenerally, for a particle size of 1 micron to remain entrained, the gas velocity should be in the range of 2.5 to 4.5 m/s, depending on the pipe size. Measures to prevent low velocities In intermittent or batch transfer operations, when demand is low at the receiving station, continue pumping at the same high rate as required for peak demand ... WebFor water-like liquids with no entrained solids (for example: chemicals, paints, petrol, beverages), a pipe velocity of about 1 – 2 m/s is considered an acceptable value. If a system contains any narrow pipes or other constrictions, the pipe velocity will be a lot higher at these points. If the liquid is shear-sensitive or can foam or change ...
