It's about air resistance

  1. Nov 25, 2011 #1
    Hello Everybody.

    I have a problem.

    I study calculate air throw distance for FANs. How can I calculate it?

    So I have some data below.

    Fan Diameter
    Volumetric flow rate (m^3/h)

    Please send me note or documents If you have any.

    Thanks for your help.

    I did some internet search and found only this.
    Note that they say the formula is applicable for only "their" fans.

    Maybe Ashrae has some info for HVAC systems regarding a single fan.

    Thanks for your intertest.

    As you motioned that formula given by Hartzellan Co. for only their Fans.

    I try to calculate with Newtons First Laws (Motion in One Dimension or Two Dimension).

    But I need coefficient of friction between air and air.
