Tomorrow target is to get outer corners and ready glasfiber layer to whole inside so I can add water. Still wondering will I buy boat electric motor or build similar wheel like here any ideas which would be better? that wheel is no problem but how to be able to control rotating speed is a problem and also at what speed :/.
Costs so far:
Glues 25€
bolts 20€
wood 15€
glasfibers stuff 15€

This would be a water 'table',rather than a wasserkanal/water tunnel.
Your flows would be only 2-dimensional and it would be impossible to evaluate wake flow.
You can analyze center-line body flow though.
Texas Tech has a water table.They pump water to an upper reservoir where the water bleeds through a porous media onto a slightly slanted backlit glass sluice.The water flows down by gravity.Simple!
