Mathematica Plotting streamlines using Mathematica

[hanson]

Can one plot the streamlines of a fluid flow using mathematica?
I never tried mathematica, actually none math software like that, so I'm sorry if this is a stupid question.

I don't see why not if you have a function definition. Depending on what you have you may be better with a field/vector plot or something along those lines (pardon the pun). Mathematica is a very useful and capable tool.
