Measurement points for fan performance curve

  1. Oct 23, 2014 #1
    For finding fan performance curve where better to put static pressure probes - near the surface or near the center of the duct ?

    I think it would depend upon the application that you want the fan for. You would need to specify your own measurement conditions to suit what you want to use it for. Is the relevant parameter the volume shifted per second or the speed of the air flow in m/s?

    Volume. Should turbulence in some points of the duct add some dynamics to static pressure being measured by the probe placed right perpendicular to flow ?
