The Q&A is actually equally informative if not more useful than the talk! Too bad it is audio only. Here are some notes I took from the Q&A: Design safety factors: material max allowable tensile stress/3.5, yield stress/3 are some common safety factors; Impact testing is usually conducted on a coupon, destructive testing is for valves and fittings A valid fitting UM stamped registration is good for 10 yrs. The RT tests applied should be based on both the type of fluid cat (for instance, cat M requires RT-1) and the requirements of the user/buyer of the vessel. BTW someone gets Ani a better pair of headset! lol his audio is terrible.

I hope someone got a better headphone for Ani. His microphone was terrible.

Well explained and the video is articulate. Thank you :)

Volume is way to low. Even when I set it to 100%, I can barely hear it.

Animations are out of the world

That colored two vane impeller looks cool and I bet that's exactly what the pump industry was looking for; An impeller that does not efficiently use centrifugal force to move water. PLEASE ... think critically and concentrate on what these colors are saying. BLUE - Suction that's great however it's pulling water toward the outer edge of the disk; That is NOT centrifugal force, that is the impeller trying to PULL the water through the impeller. GREEN - Recirculation What the hell is that? It's also NOT centrifugal force, it sounds like a waste of energy. RED - the tail end is at such a slight angle it's trying to PUSH the water out of the pump; THAT IS NOT CENTRIFUGAL FORCE ! ! it's a Blade PUSHING THE WATER OUT. CENTRIFUGAL force is WATER GAINING ENERGY by SPINNING and then the WATER, in and of itself, PULLS itself Out of the rotor, . . . I hate to point it out, but Tesla turbines used as pumps DO NOT CAVITATE and if they did, the collapsing bubbles would do little damage because the impeller blades never harshly impact the fluid. Maybe one of you can explain to me why disk impellers are not used in modern pumping applications. Thank you for your great videos and I truly hope you can set me straight on this disk type impeller thinking.

QUESTION: when the tube or Pipe, is large enough to overcome capillary action; would the flow after the first peak simply drain through the bubble by gravity? Therefore allowing at least a minimum flow around the bubble?

Most enjoyable lesson. thank you.

I hope more of these types of videos are done, I’m a PE and this is better than near everything I’ve seen on these topics

I want to know what John Brooks company does

This was such a great video covering pressure vessels and all the testing requirements. Both parts were very helpful.

Thanks for sharing.

Thank you for this presentation. I was taught this method in college. Your presentation was very thorough and helpful.

Any info for viscosity effect on axial flow pumps?

less particulate in your Compressors intake Suction stream will increase the Life Span of your Compressor, because of less wear and abrasion.

you can refrigerate the compressed air vapour stream below the atmospheric freezing point of water, without the risk of ice freeze up, because the freezing point of water will decrease under increased pressure. just the same as the condensation point of water will decrease in turn..

Thanks

Great

Very informative session. I am a mechanical engineer based in India and currently train mechanical engineers at different corporates on various topic including the pressure vessels. I approve each information provided is completely correct following quality standards in manufacturing. Suggestion: Basics of pressure vessels should also be addressed for the general people seeking knowledge on this topic.

This presentation was seriously great.

Hi What will be the reading of the current and the pressure and quantity of flow on indicators in the station when the main line water of city is broken

Great Video Guys explained things very clearly and simply. I have just set up some bookmarks for future reference. 17:46 HGL on line with High Point 20:23 Siphon about to be setup 25:00 Pressure below zero as HGL below pipe line 26:06 Pump Booster of HGL 26:33 The Monster Transients from Siphon 29:45 Pumping against Siphon 30:00 HGL example with negative pressure and pipe collapse 32:00 Air Break Valve Operation 34:32 Air Break Valve 41:51 Cannot relie on Siphon being their 43:00 Questions - Transition from pressure to gravity flow 47:53 commonly called "Flow Away"

[please elaborate on what actually is a pressure vessel. It must be above 1 bar, and must be of a certain size, and have certain features, what are those?

Thank you! :)

Have to say. The quality of presenters at John Brooks is damn great. Stefan, Chris, and now Anita ❤️❤️ The videos are very helpful and informative and I feel the quality of instructor also matters a lot.

Damn..this is handsdown the best video for centrifugal pump on RU-vid. This should be included in every chemical engineering pump course. Thanks a lot guys ❤️❤️❤️❤️ very very insightful

@26:19 air entrainment, nice one, I assumed it was cavitation. Inaccurately.

@25:26 the water line is under the suction so the head is negative, you add yes, but the system curve should go down not up.

Very a great lecture, I learn a lot form it, very clear and logic. I appreciate it.

This guys webinar is like a cheat code or something, thank you so much for making it so clear and letting us understand the principles rather than memorizing. Thanks Stefan!!

very in-depth webinar! thank you well done!

Very nice excellent explained very fast to remember what you have explained

being searching for this type of video...thanks...now i m more confident in designing multi point pumps....i wish u well...

My hydraulic mind was blown

From Mexico, thank you very much!, nice explanation.

How to access your free webinars

Thank u for this Work

✌✌✌✌✌✌

Thank you

11.01 for Design Thickness calculated, how did you get P=201.66?

Thank you so much for your teaching with it !

Thank you so much for your teaching of it !

Very nice. I am a technical support engineer at Hexagon the creators of PV Elite CADWorx and Caesar II. You highlighted safety which is the first and foremost responsibility of the engineer, together with the responsibly of following the pressure vessel code as far as all its rules are concerned - very important. You covered the main points.

Please,l am mechanical technician, a water centerifughal pump when started the few minutes late water pressure t low. please tell me this error

Great video, Thanks!

hello i have a centrifugal pump suction end pump that is cavitating how can i purge the air bleed the air out of the system .

This video is highly underrated. Thanks for this video

Valuable info
