Maximum Flow Velocities in Water Systems

Water velocities in pipes and tubes should not exceed certain limits

The fluid flow velocities in water systems should not exceed certain limits to avoid noise and damaging wear and tear of pipes and fittings. The table below can be used as guidance to maximum velocities:

Application Maximum Velocity
(m/s) (ft/s)
Tap water (low noise) 0.5 - 0.7 1.6 - 2.3
Tap water 1.0 - 2.5 3.3 - 8.2
Cooling water 1.5 - 2.5 4.9 - 8.2
Suction boiler feed water 0.5 - 1.0 1.6 - 3.3
Discharge boiler feed water 1.5 - 2.5 4.9 - 8.2
Condensate 1.0 - 2.0 3.3 - 6.5
Heating circulation 1.0 - 3.0 3.3 - 9.8
