I am interested in the recommended velocity in liquid pipelines. API 14 in table 2.3 states for suction line 2-3 ft/s and discharge 6-9 ft/s for centrifugal pumps. But my question is about pipeline pumping light naphtha, if the same figgers are applicable or not, as it is volatile liquid.

Somewhere I read it should be between 0.9-1.8 m/s. Is there a source for this recommendation somewhere? Thanks

Hi,

Consider these resources.

Often the requirement is expressed in Head loss, see table and standard shared.

note:

Pay attention to the risk associated with static electricity built up in pipe due to high velocity!

Some companies are using anti-static agents.
