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.
