    Thumbs down Duct Design



    HI
    I was wondering if some1 has a simplified yet comprehensive e-book for duct design

    Hello pal.

    Click HERE for a starting point.
    It takes you to Ventaxia (the fan manufacturers) website. The e-book in the link is a very good guide.

    All fittings in duct work as in piping have pressure drop equivelents to what is called straight duct or pipe
    EX: say a 45* fitting would be say the equivelent of 25 feet of straight duct or pipe

    Re: Duct Design

    well all the link emphasises on circular duct
    i think when u know the standards of velocities to be maintained on supply/exhaust diffusers and branch and main ducts then all that is left is mere calculator to ensure required cross sectional areas with length and height.

    Can any1 give me a chart to elaborate what impact different bends(90*,45*0 have on static pressure?
