1. The problem statement, all variables and given/known data 2. Relevant equations Given in problem 3. The attempt at a solution Hey guys So I have this problem I'm working on and I just can't seem to get too far with it. I've gotten half of the first part...I'm just having trouble integrating the equation I got...and I don't even know if the equation I got is right in the first place! I set: Rin = pi Rout = pi(20h-h^2) dh/dt = Rin - Rout I'm trying to solve the DE right now but don't know how to proceed... Any help would be great, Thanks.
