what is it?
At this site you will find a picture of a focault pendulum clock that
has a cone shaped piece of metal from a hydroelectric generating station. nThe metal is 'said' to be really hard, but it has been abraded/contorted into a very interesting shape. The question is....what part is it, what was it's function? It is interesting to note that the very tip shows little deformation/abrasion; could it be the 'end' instead of the 'point' of an apparatus in the flow of water? rick http://www.betrisey.ch/epointe.html |

The deformation will have taken place primarily in the seating area below the tip where the fluid velocity is highest. Bernoulli would have us believe the pressure falls as the velocity increases so I suspect that at high flow rates the fluid was cavitating there leading to the interesting shapes worn into the metal.

I'm quite grateful they do though. |

what is it?
I think it is the exhaust cone on a water turbine, It's purpose is to reduce
cavitations ? bill k |

The water didn't dissolve the metal. Cavitation erroded it. Dave What size particles are you talking about in the errosion process? By that I mean what would be the average particle size of the metal as it leaves the surface of the cone? rick |
