If thats true then i would like to take that 1.2 MW electric motor and build another one using a lot less energy that you can use instead and give me some of the money you save on electricity.. I mean, seriously? It cant take 1.2 MW to drive a 2 meter impeller to give 18 m/s water flow? Or is it like instant 18m/s because then i see it needs a lot of RPM to get that flow rather quickly.. Are you sure its 1.2 Mega watt? Like a rather big windmill :S
@hede88 It is actually true, it is a 1.2 MW electric motor that powers the propeller.
If you google "Marintek cavitation tunnel", you can find all the specs on SINTEF's webpages.
It takes a lot of power to move such great amounts of water. It is only in the working section that the water reaches 18 m/s, and the diameter there is "only" 1.2m. Still, that means that more than 20 m^3 is pumped every second!
very good

Okay, pretty cool.. I'm making a hydrofoil kitesurf board, wish icould test like that

Love the experiment, well done guys..
