Easy fluids problem.

  1. May 9, 2007 #1
    1. The problem statement, all variables and given/known data

    a. Given potential flow, find stream function and velocity components.
    b. Compute pressure along the x-axis and plot it.

    2. Relevant equations

    Psi = 2axy

    3. The attempt at a solution

    So, I got the psi from phi (above) but i dont understand how im to go from stream function Psi to the pressure distrobution...

    From the stream function you can calcualte the velocity field.
    You can guess that it is possible to get the pressure, just think to Bernouilli.
    Anyway, plug the velocity field into the Navier-Stokes equations and you will get the pressure (gradient).
