As a rule of thumb the following velocities can be used in design of piping and pumping systems for water:
|NPS||Max. Delivery Velocity|
Pipe lines - fluid flow and pressure loss - water, sewer, steel pipes, pvc pipes, copper tubes and more.
Dimensions of pipes and tubes, materials and capacities, pressure drop calculations and charts, insulation and heat loss diagrams.
Piping systems and pumps - centrifugal pumps, displacement pumps - cavitation, viscosity, head and pressure, power consumption and more.
Hot and cold water service systems - design properties, capacities, sizing and more.
Recommended max flow velocity on the delivery (pressure) side when pumping boiling liquids.
Recommended max. flow velocities on the delivery side when pumping light oils.
Recommended max. suction flow velocities when pumping light oils.
Typical fluid flow velocities for common liquids, gases and vapors.
Calculate fluid velocity and volume flow in pipes and tubes.
Water flow in thermoplastic PVC and CPVC pipes Schedule 80 - friction loss (ft/100 ft, psi/100 ft) and flow velocities at dimensions ranging 1/2 to 16 inches.
Maximum water flow capacities in steel pipes - pipe dimensions ranging 2 - 24 inches.
Velocity head can be used to calculate minor pressure or head loss in fluid flow systems.
Recommended max. flow velocities on delivery sides of pumps in viscous systems.
Recommended max. water flow velocities on suction sides of pumps.
Reynolds number for clean cold water flow.
Water velocities in pipes and tubes should not exceed certain limits.
