My disparaging remarks are taken out of context! I blame the clapped out Bridgeport.

cAvEtation? I have no idea what that means but loved the video.

[DIYBuilds]

I had no idea that AvE video i watch all that time ago was for you. Great colab guys.

Arduino versus Evil.
That's like finding out Kramer's first name.

What an awesome surprise to see one of our favorite channels use our gauge!!! It looks like you could use a differential pressure gauge with a higher range. Would you want us to send out a free gauge with a 0-30PSI range? (we also have a 20 and 40)

When Grady said this was an international collaboration between Canada and the United States I assumed he was the Canadian since he seems so polite and wholesome and AvE was American given his blunt sense of humour. Upon viewing Grady's profile and discovering he is from Texas I learnt a lesson about prejudice :P.

Can't believe I am just finding this now. I love both these channels, but am surprised to see them together. They are both pretty clearly typical engineers, but from opposite ends of the sanity spectrum.

Worked as a throttleman on a submarine in the US Navy, we used venturi to draw vacuum in condensors. Also had to listen to hydrophones to make sure that we did not cavitate.

I love AVE been watching for years, why is Youtube just now showing me this vid? You have an awesome channel too. Big fan!

Grady: Proceeds to drawing with much time and care.
AvE: "Look at that worthless sh* drawing".

I love that you simply acknowledged the criticism and moved on, without spiraling into a cycle of self pity and doubt. That’s an engineering skill that can’t be taught, but a necessary skill as there’s always gonna be someone better qualified who’ll tear your work apart, along with your spirit, and you just gotta pick up the pieces keep moving along.

AvE is one of the smartest people I've ever seen. His channel is too good

Great video and explanation, but I thought that I should point out that most of the bubbles you are creating are from the dissolved gasses in the water. This is observed by watching the bubbles and how far they travel past the area of low pressure. If they were purely water vapor bubbles they would collapse much sooner. The dissolved gasses coming out of solution are what prevent a lot more damage from being done to equipment such as boat propellers, because they cushion the vapor bubble collapse. When you have a system such as a condensate pump where the air and noncondensable gasses have been removed, the vapor bubble collapse can be much more violent and destructive.

You make fluid mechanics a practical and fun topic that invites you to watch your videos. The general opinion says that if someone took the time to prepare and share something special, it is up to the rest of us to offer the courtesy of seeing it, thank you for your generosity. ...

Thanks for sharing. There was a documentary on water cavitation where they used cavitation to really efficiently heat water, it was a spinning cylindrical rotor assembly with lots of shallow round holes, encased in a tight fitting round housing with an inlet and outlet for the water and while rotating, the water passed through and underwent cavitation and rapidly heated in the process. I think the docco was called “Equinox it runs on water”

Interesting demo.
My dad worked in the water treatment/delivery business for over 40 years. His specialty was back-flow protection, but he also had to deal with cavitation issues. I learned a lot from him about these subjects as a kid, sitting around the dining table.
Some of the pump "guts", both large and small, that I got to see were pretty amazing.
Hard to imagine if you haven't seen some of it.

You take criticism really well and the quality of your videos is always spectacular! Also thank you AvE for all the hard work!

What the term 'Cavitation' brings to mind is submarine props making noise that can be detected with sonar (by the enemy)... I grew up near the Kings Bay sub base and their props are well hidden to hide their design.
This video did help me understand how "Cavitation" happens on a sub prop!

I remember watching the machining video and wondering what the destination was...awesome collab!
