# Thread: Help with funky integral

1. ## Help with funky integral

Hi there,

I need help with a funky integral in fluid mechanics. Its been a while since I took calculus, so I just need to figure out the steps taken to solve this one:

$\rho V^2 \pi \int{\frac{1}{4m - \rho D^2 \pi \sqrt{2gz}} dz}$

Thanks

Your integral can be put into the form $\int \frac{1}{a - \sqrt{x}} \, dx$.
