Brilliant video. One question - when cavitation occurs, will we always see this significant drop in pump head (greater than 97% drop) relative to normal operating conditions? Would this be a good troubleshooting indicator for cavitation in pumps? Can we have a scenario where you reach cavitation within the pump, but the fluid gains enough pressure to go higher than vapor pressure just barely at the discharge at the pump, hence the manometer-vacuum reading doesn't drop to 3%?
Great video ❤. Very informative
Thank you, @katuraysalad!

It is Pi abs which is in different color at 4:23. The absolute pressure at eye of the impeller.
Thanks for your comment!
