    The document provides recommended velocity ranges for different types of water systems and pipes to minimize erosion and damage. It recommends velocities of 8-12 fps for pump discharge, 4-7 fps for pump suction, 4-15 fps for headers, 3-10 fps for risers, and 4-10 fps for drain lines. For smaller pipes the recommendation is approximately 5 fps, and for larger pipes 8-10 fps. It also provides maximum velocity recommendations based on the number of annual operation hours to further minimize erosion.

    Recommended Water Velocity

    -------------------------Pump discharge - 8 to 12 fps


    Pump suction - 4 to 7 fps
    Header - 4 to 15 fps
    Riser - 3 to 10 fps
    Drain line 4 to 10 fps

    (2,44 to 3,65 m/s)


    (1,22 to 2,13 m/s)
    (1,22 to 4,57 m/s)
    (0,92 to 3,05 m/s)

    SMALL PIPES: aprox. 5 ft/sec ( 1,52 m/s)


    LARGER PIPES : 8 10 ft/sec (2,44 3,05 m/s)

    Maximum water velocity to minimize erosion based on normal operation in hours / year
    --------------------------1500 hrs/year - 15 fps
    2000 hrs/year - 14 fps
    3000 hrs/year - 13 fps
    4000 hrs/year - 12 fps
    6000 hrs/year - 10 fps
    8000 hrs/year - 8 fps
    Velocity is only one part of the selection. Also check the friction loss in feet of water per 100 feet. I
    normally use in the range of 1.5 to 6.
    ___________________________________________________________________________
    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
    Tap water (low noise)
    Tap water
    Cooling water
    Suction boiler feed water
    Discharge boiler feed
    water
    Condensate
    Heating circulation

    Maximum Velocity

    (m/s)
    0.5 - 0.7
    1.6 - 2.3
    1.0 - 2.5
    3.3 - 8.2
    4.9 - 8.2
    1.5 - 2.5
    0.5 - 1.0
    1.6 - 3.3
