Hmm thanks guys for the confirmation. I believed it to be: w=z*exp(-i*alpha)+(exp(i*alpha)*b**2/z) as it says but my program still doesn't work. It can plot zero incidence fine but then goes crazy and makes weird sausage things when I add incidence... oh well I'll sleep on it maybe

Does anyone know what the conformal mapping of an aerofoil at incidence is? Does it use the Joukowski transformation? Or something else.. Thanks

wouldnt this also be true: F=ma F=6(pi)rnv 6(pi)rnv=ma m=dv m=p4/3(pi)r^3* a=[ 6(pi)rnv ]/m a=[ 6(pi)rnv ]/ p4/3(pi)r^3 a=18nv/4r^2p sorry for the crude typing, i don't have your fancy equation generators cheers

Wow hi Thank you for replying! The main problem i had was that i have no information about the ball at all apart from the fact it is steel and i no nothing about the dimensions of the tube. All i have is the viscosity. I will look into what you have given me and also i am writing a program...

Hello Everybody! Er well I'm new to this forum so hi guys! I have a small problem which is made even worse by the fact i know very little about the subject. Ok the problem is about steel ball bearings falling through a liquid. The Situation: A wide cylindrical plastic tube 1.0 to 1.5...
