Can someone Help me with Dimensional analysis please

  1. Aug 24, 2007 #1
    I have this queston:

    The flow rate in a pipe is assessed by measuring the speed of rotation of a propeller having its axis along the pipe centre-line. Show by dimensional analysis that the volume flow rate, Q, is given bu the expression:

    Q=(D^3).N.Phi.(d/D,(density.(D^2).N)/viscosity)

    where D= diameter of the pipe,
    d=diameter of the pipe
    N=the rotational speed of the propeller

    I'm very confused as to how to go about this, any help would be appreciated.

    Have you read up on the Buckingham Pi Theorem?
