This subect matter is covered in Introductory Hydraulics courses in engineering schools. Find a free hydraulics ebook to download using Google Search, unless you already have such a book.

Also, another very good source is Limbergh's "Fundementals of Engineering Review Manual" which is used for studying "Part A" of the Professional Engineering Exam.

Also, Merritt's "Handbook of Civil Engineering" covers the subject well.

Additionally, find Brater & King's "Handbook of Hydraulics" textbook. This is a very good book to have.

All of the above mentioned books are available as free downloadable ebooks in PDF format.......you have to search high and low to find the free links...dig dig dig!

I can say one thing. You do not know what you are talking about

Looks like you did not know it in the first place. The way I see it you dismiss Mosies answer because it does not spoon feed you the answer but has you DO something to find the answer. Did you check out the given sources and did not find what you where looking for? Come back when you have done so.

I was intersted to see the answer on this but you are the one that really needs it, right? So better step up the effort and let us all know what you find!

Thanks IS

I have to dismiss because he mentioned hydraulics. How the vessel mechanical design is related hydraulics. However, I apologize, if it hurts him

Hydraulics HAS everything to do with this problem. Water (or some other fluid that you're using in this process) is flowing through the nozzle(s), correct? In order to properly design your vessel you first need to be able to calculate the forces imparted from the flow of water through the nozzle.......vector analysis calculations primarily, which leads to determining applied bending moments. Come on now, this is elementary Engineering Freshman year course material! If you area Mechanical Engineer (or student) you should know this stuff by now.....

Is it a straight nozzle or a nozzle with a bend in it? A lot depends on the configuration of your nozzle(s)....actual geometry counts! So does internal pressure of the liquid!

I'm not going to spoon feed you the answer to your query. It is entirely up to you to figure out the solution. As it is, I've already given you a direction to follow, so now it is up to you to search through textbooks, handbooks and the Internet to further your search.

You sound like some of my past Undergrad Students that were too lazy to crack open a course textbook and actually learn something by reading that very same book....instead they wanted to be spoon feed, but you do not learn anything that way, right?!

For your information, I am professional doing pressure vessel designs every day. I do not know your back ground . I think you are good at imagination.

I am in serious business here and not doing home work as you may think. Neverthless, thanks for your feedback.

You and Captain Moosie are from 2 different cultures. If you don't know what something means, please check it out.

Captain Moosie gave his credentials, will you?

My Credentials, if you please:

BSCE: Major: Civil/Environmental Engineering; Minor: Structural Engineering; Rochester Institute of Technology (RIT), Rochester, NY, USA.

MSCE: Double Major in Civil/Environmental Engineering & Structural Engineering; Rensselaer Polytechnic Institute (RPI), Troy, NY, USA.

Ph.D & Post Doctorate: Emphasis on Environmental Engineering, primarily in Water & Wastewater Treatment Design, Analysis, & Strategies; Carnegie Mellon University (CMU), Pittsburgh, PA, USA. Want a copy of my Thesis & publications too? LOL

Former Captain, US Army/USAR. Served 11 years in the US Army Corps of Engineers in Seattle WA, New Orleans LA, Vicksburg MS, Rock Island, IL USACE Regional Districts (Heavy Civil Works Design, Analysis, and Construction Liaison). Also, US Army Rangers, 3 years Active Duty. MOS 11B (Infantry) & cross-trained MOS 21B (Combat Engineer). Recipient of the Silver Star (amongst other awards and commendations), and twice a Combat Vet.

I've been a Civil Engineer for 35 years, 17 years as Licensed Professional Engineer in New York State.

I have worked for numerous consulting engineering firms throughout my career, some of which are ENR Top 500 firms. Also, I was a City Engineer for a small upstate New York City. I have previously been a member of a County Planning Board. I presently am a member of our Village Planning Board, as well as a Technical Adviser for our County Planning Department/Federation.

Is that enough for, or should I continue on?????

Okay wise-guy OP, what do you bring to the table? This is getting very tiring listening to your drivel.....

[Many thanks DDK!!! . It's obvious that the OP is "totally clueless". eh?]

So you say a Nozzle is a mechanical device and further down you call yourself a professional?

Good luck with your next job.

I forgot to mention the following:

Member, American Society of Civil Engineers (ASCE) + Mohawk-Hudson Regional Chapter of the ASCE.

Member, National Society of Professional Engineers (NSPE) + New York State Chapter of NSPE.

Member, American Water Works Association (AWWA) + New York State Chapter of the AWWA.

Member, Water Environment Federation (WEF) + New York State Chapter of the WEF.

Spare your words, as long as the nozzles are not HIC tested he never gets this done professionally! http://cr4.globalspec.com/thread/78155

The principal load on pressure vessels and nozzles is usually from the fluid pressure involved. Fluid flow seldom introduces comparable forces, except in cases of liquid hammer. What the OP is interested in is external forces on nozzles, such as weight of items partly supported by the nozzle, temperature expansion/contraction, vibration, piping strain from poor alignment, etc. I doubt this would be covered in a basic course on hydraulics.

Tornado is right and that's what I am trying to say. I request CaptMoosie not to judge people. Your credentials does not matter, if you don't understand the question. Let us close the discussion

I'd agree with Tornado's #12, though I'm not sure what you mean in original post by "the nozzle loads on supports."

But with ref to nozzle moments, an old copy of BS5500 I have doesn't help much, unless I'm missing something. It describes how to add a reinforcing plate around a nozzle, but this is so the vessel shell can still take the pressure, after a piece has been cut out for the nozzle. It doesn't mention the stress in the shell due to a nozzle moment. Maybe newer vessel specs cover it, but if not, try e.g. Roark. In my old copy (another one!) it's Table X, Case 10. This is for a moment applied to the centre of a circular flat plate, so not exactly like a vessel shell, but should give a good idea of stress.
