I'm stumped on a HW question that I just can't seem to proceed on. 1. The problem statement, all variables and given/known data An incompressible ( rho = constant ) flow in 2 dimensions [x = (x,z)], with F = (0,-g), satisfies Euler's equation. For this flow, the velocity is u = (u0,w(x)), where u0 is a constant, with w = 0 on x = 0 and p = p0 on z = 0. Find the solution for w and p, and show that it contains one free parameter. 3. The attempt at a solution I've managed to get p(z) = p0 - rho*g*z, though I don't really know where to go from there or if I've even done it right to begin with. Any guidance would be much appreciated, thankyou.
