Re: Water tunnels and dynamic similitude (help!)

This might be more useful to you. I know that there are flow tanks capable of sustained flow above the maximum aerobic swim speed of some fairly large, athletic fish (salmon, chub), because in my field we use them for exactly that. I'm not sure if the top speeds are enough for your purposes, but I ...
