Speed of water at a certain poinmt in a pipe

[merrittr]

Hi

I was wondering how to calculate the speed of the water at a cetain point in the pipe

(i assume that all the water at that radius is going at the same speed due to laminar flow)

Yes it will be going at the same speed. No it has nothing to do with laminar flow.

You just solve the cylindrical Navier-Stokes equation with the appropriate boundary conditions and you will have a nice analytical answer for your profile in the pipe.
