Essay of fluid dynamics for IB diploma

[Srinand]

I'm planning to do an extended Essay for the IB Diploma in Physics. I want to do something on Fluid Dynamics. I was thinking of investigating terminal velocity and effects on drag and upthrust to terminal velocity. That investigation will of course involve Stoke's Law. BUt I think that might be too shallow and GCSE-type of investigation. Can any of you suggest questions concerning fluid dynamics and post them here. Essay titles from the past that have acheived high grades would also be helpful! Please help!
