Speed control should be fine with an electric motor
In the film the water is flowing rather slowly when you see the flow tank - until the aero shapes are shown, then the flow is faster, though I think these are sped up after recording.
Wouldn't the Reynolds number combined with the viscosity determine your water flow speed range ?
