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 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?
It would be very informative if it’s possible to make demonstration when water level goes below water pump level and how to provide suction when water level is below pump
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
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.

The best demonstration ever. I always show it to my students in Brazil. Congrats!
Watching this and listening to you speaking so calmly was a stressful experience. Thanks.
Excellent demonstration, thank you. I feel bad for that pump.
Thank you finally I understood the cavitation. This is gold.

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 explanation and demonstration!
"And that's a happy pump" xD
Great demonstration of cavitation. Thanks for postin this video.
Thanks for the explanation! Very interesting!

Excellent !! I would like to buy this whole setup for Research purpose... I am from singapore.... How do i buy this setup??
Hi, was wondering if discharge valve is slightly shut and the pump is running will that too cause cavitation to build up ?
thanks for the video.
Well, how can we improve or get rid of cavitation( in orifice or venturi)?
Very interesting and very well explained thank you
Thank you!

Excellent 👍
Well explained. Thanks.
I liked your upscale page posts

What is the pump model and valve type used in suction side?
Excellent Demo....!
Great thanks for explean expermantal the cavation
Excellent, thanks!
You can ealisy hear and find this kind of problem on a pomp thanks to the ultrasounds !
Check our youtube channel !
tube probably feels cold too?
why the manometer has pressure when there isnt flow?
USER SDTUltrasound to measure the cavity . a very advanced and easy tool//
enfin, on voit ce qui se passe vraiment

Mucho betis
BE AWARE OF THE RADIATION!!! MEASURE IT WITH DOSIMETER!
Radiation? From what??
From annihilation. Dosimeter is your friend.
