Easy Fluid Problem: Find Stream Function & Pressure

[600burger]

Homework Statement

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

Homework Equations

Psi = 2axy

The Attempt at a Solution

So, I got the psi from phi (above) but i don't understand how I am to go from stream function Psi to the pressure distrobution...

From the stream function you can calculate 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).
