    Calculating the power output of a variable speed fan

    [​IMG]
    Just looking for some help with this,

    I have an axial flow fan connected to a variable speed drive set to 50hz, what I need to know is how to calculate the power output of the fan at any given frequency between 0 - 50hz.

    Details of the fan are as follows:

    3phase 400v

    P=2900W
    I= 4.9A
    n= 1350min-1

    FOR Calculating output power P=V*I*(sq.rt of 3)*efficiency*power factor

    i think am correct sorry if am wrong😉
