I can't believe this video has been around for over a decade and I've never seen it. This is the most informative demonstration I've ever seen for cavitation.
Increase the static pressure so that the minimum pressure never falls below the liquid's vapor point; decrease the temperature to depress the vapor's flash pressure.
Is it possible for cavitation on an outboard engine to cause a noise like this at 2-3 mph ? But smooth any other speed. Or does it need to be in a closed system for that noise
is there a formula to determine the reduced pressure from the inlet due to closing of the inlet valve? or do you know any paper explaining the pressure drop due to the closed valve?
Be careful, that cavitation you see just after the suction valve is caused by the pressure drop through the valve not the pump...sending them to the pump.
you should be careful doing that. Due to the Leclaire effect you can be producing gamma waves. you should do the same experiment but with a Gigacounter running nearby.

Excellent demonstration, thank you. I feel bad for that pump.
Watching this and listening to you speaking so calmly was a stressful experience. Thanks.
The best demonstration ever. I always show it to my students in Brazil. Congrats!
"And that's a happy pump" xD

Great explanation and demonstration!
It's interesting to see this with a clear pipe system.
moi je suis superviseur de dewatering dans une mine alors jaimerais faire une formation de renforcement de capacite
Great thanks for explean expermantal the cavation
Thanks for the explanation! Very interesting!
Great demonstration of cavitation. Thanks for postin this video.
Excellent 👍
Very interesting and very well explained thank you
Well explained. Thanks.
I liked your upscale page posts
Thank you!
Excellent, thanks!
Excellent !! I would like to buy this whole setup for Research purpose... I am from singapore.... How do i buy this setup??
Excellent Demo....!

thanks for the video.
Well, how can we improve or get rid of cavitation( in orifice or venturi)?
You can ealisy hear and find this kind of problem on a pomp thanks to the ultrasounds !
Check our youtube channel !
USER SDTUltrasound to measure the cavity . a very advanced and easy tool//

enfin, on voit ce qui se passe vraiment
What is the pump model and valve type used in suction side?
you should be careful doing that. Due to the Leclaire effect you can be producing gamma waves. you should do the same experiment
but with a Gigacounter running nearby.
tube probably feels cold too?
Mucho betis
why the manometer has pressure when there isnt flow?
BE AWARE OF THE RADIATION!!! MEASURE IT WITH DOSIMETER!
Radiation? From what??
From annihilation. Dosimeter is your friend.
