I've been still looking at the problem too, and I think I noticed that in the example solution I gave: ωz = (1/r) ∂/∂r (ruφ ) = (1/r) ∂/∂r (r2Ω) = 2Ω it seems as though it was solved like a regular differential equation using only the rule for the derivative of powers: If f(x)=xn, then...

Out of the 3 cylindrical coordinates, there is only vortical motion wrt z, which motion is dependent on r, as the equation shows, I think.

Hi, sorry, guess the thing on the other side would matter. It happens to be vorticity or, in cylindrical coordinates, ω_z.

Hi, I'm doing some research on my own, but my math is pretty bad and I am stuck trying to find the solution to this problem: (1/r) ∂/∂r (r√(C/r))= I've seen these solutions of similar-looking problems: (1/r) ∂/∂r (r^2 (Ω))=2Ω and (1/r) ∂/∂r (r K/r)=0, except when r=0, in which case the...
