Will compress model a vessel of non circular cross section such as a rectangular or square vessel?

One of the pump vendors has produced the sought after curves. smckennz, The pumps are in a 24hr service and several states away. We have in the past taken measurements and plotted our own pump curves but only after exhausting other resourses, like this one. Thanks for your reply. DDS1

Valleyboy, If I read your post correctly we call it dura-wall. DDS1

dmsbeam, Ductwork is a broad word. If you are looking for light hvac type then the previous posts are probably a better fit. If you are looking at stiffened plate steel construction as in boiler breeching etc. for industrial applications you can look at Design of Weldments or Design of Welded...

Saxon, Thanks for your reply. We had contacted our local rep. for flowserve and he is looking for the curves. I should have elaborated a bit. The pump is a number of years (decades)old. We had hoped that like many other dated lines someone had aquired the casting rights and were still...

I need pump curves for Ingersoll Rand APL series pump. In particular 12 and 14. My real question is who now represents the APL pump line. It appears Ingersoll Rand no longer markets the APL series. Thank you, DDS1

Geoman, My experience with clean crushed stone (from the midwest) is 1.15-1.2:1. Of course, I too first came across these numbers from the gravel pits owners. A good point mentioned by DRC is that the loose volume to compacted volume for clean crushed gravel is not as significant as that of...

I have received a list of welding electrodes required to weld together a piece of germany processing equipment(for a bid thats due back by tommorrow). The electrodes of course are EN (european standard)designations. I want to price rods of AWS designation. Does anyone know of a online...

I am in the midwest but have paid out when we were busy and have billed for our services approx. 30-35 hr for drafting services and 60-70 hr for engineering and design. If you have little overhead and want to appear reasonable then 30 and 60 are fair. For what its worth DDS1

My understanding is that of ERV posted above. For shoring in excavations over a certain depth an engineer is required to review and/or design the shoring. I have never known OSHA to govern form design. What is the material of construction of the forms? What is your whaler and/or stiff back...

Azonicbruce, No, you shouldn't remember everthing you learned in college. Therefore the comment on good reference material. You hopefully have your college textbooks but this is only a start. One of my most valued possessions is the library of reference material I have accumulated through...

Azonicbruce My curiosity is with Focht3. I have been following the posts and was wondering who made the final decision. When I first read your post I was sure you were going to get "beat up" for practicing outside your area of competance. For the most part everyone was helpful and...

rmw, I appreciate your taking the time to follow up as mentioned. I don't disagree with your first response that a "good" reputible shop would/should know the requested information. I however do not like to rely on the fabricator (which is a contractor) to provide such information...

I am currently working on a retro-fit of a calandria type evaporator. I am fast tracking the project and am wanting to get my preliminary design to fabricators for quotes. I have ordered a TEMA standards book to reference the information I need but want to send out prints before the book...

This issue has surfaced several times in my career. The philosipy of my mentors and now my own has been that this is bad engineering practice. If you reference AISC manual of steel construction (at least he ASD additions) they do not include in their tables tabulated values for a single bolt...

Depending on the application of course, certain steel sections have inherent properties with regard to their geometry that make more desirable. From a true fabrication standpoint the WF sections offer the advantage of bolted connection that require a minimal amount of shop welding. That is...

It could also be possible that the contractor missed his finished floor elevation and therefore added the necessary topping to achieve this.

I can't add much that hasn't been touched upon but here goes. First, it is fair to say that the floor that exists wasn't designed to hold this press (unless you are replacing an existing one) because it probably wasnt a conceived load at the time the floor was designed. And in line with our...
