It has been a while since I've had calculus. I am working on a fluid mechanics problem:
I have reduced the Navier-Stokes equation and this is what I have:
mu [d/dr (1/r d/dr (r v(angular)))] = 0
How do I solve for v(angular) ?

Hi jojoba! :smile:

(have a mu: µ and an omega: ω :wink:)

d(ωr) = Kr dr :wink:
