    Vacuum Jacketed Pipework (cryogenic duty)

    I would call BOC Edwards and places like Air Products. A few years back we had a cryo pipe project at the plant I worked in. I remember our central engineering office lacked cryo pipe specs. I took a chance and called BOC Edwards. They were very helpful, and provided us with everything we...

    Mechanical Flow Meters -- Tell me your story (good/bad)

    The only mechanical meters that ever worked in our plant were LCI mechanical meters (M-5's and M-7's). Our Neptune's never held up well. We used the LCI's with batch totalizers to charge raw materials (organics, oils, formaldehyde, etc). We even charged molten wax with them. They were good...

    STAAD vs. competitiors

    Robot was my choice, after a month of comparing features and costs. I just couldn't find a better package for what we needed anywhere else. We design and fab small industrial non-building structures (<500 elements), and do load cases and FEA on fabricated metal structures (VRU ducts, hoods...

    Venturi Vaccum Pump

    LarryC, My mistake. I gave you an old number. Use 1-732-339-9141. I also spoke to several people about you question. Let me read your fax, and I'll fax back something for you to go on. SteamJetPE Ejectors, LRVPs, Hybrids Troubleshooting, startup, design

    Annual Engineering Cost Savings

    A few years back I negotiated a raise and control of two departments using this argument. Unfortunately, I didn't keep my notes. If memory serves me, I found this info in an article that was available on Proquest.com (I was an MBA student, so I had free access). I'm almost sure it was based...

    Venturi Vaccum Pump

    Cleaner, No single equation exists that would get you the result you need. The manufacturer of your venturi should have the data in the form of a test curve. SteamJetPE Ejectors, LRVPs, Hybrids Troubleshooting, startup, design

    Online Physical Properties of Compunds

    Good luck. Back in 1998 I tried searching for a similar source to populate some data tables we were putting together for a new plant. We ended up using Perry's, the CRC, and a couple of college textbooks. You can try getting abstracts from the internet on individual materials, but back in 98...

    WRC-107 Question

    Has anyone ever tried WRC-107 to get allowable loads and moments on a flanged nozzle attached to the end of a tapered shell course? SteamJetPE Ejectors, LRVPs, Hybrids Troubleshooting, startup, design

    Anyone hear about the Jan 2002 Addenda yet?

    It's National Board, and it comes out in January. SteamJetPE Ejectors, LRVPs, Hybrids Troubleshooting, startup, design

    Anyone hear about the Jan 2002 Addenda yet?

    I'm checking further on my end. I plan on calling the NB tomorrow. To me, it would make more sense that the NB would come out with a construction code, not ASME. As for your question on public reviews, all I heard was that they were undertaken in the last four or five years. I should find...

    Pressure Vessel Software

    Look into Compress while your at it. Whatever you pick, make sure it's well supported by the software maker (addenda, upgrades, etc). SteamJetPE Ejectors, LRVPs, Hybrids Troubleshooting, startup, design

    Anyone hear about the Jan 2002 Addenda yet?

    I hear ASME is championing a new construction code governing boiler & pressure vessel installations. It will take precedence over all other construction codes. It's been through four or five public comment periods over the last few years. Comes out in 2002 as a nonmandatory appendix, then...

    Venturi Vaccum Pump

    I'm going to move to trading faxes with you.

    Venturi Vaccum Pump

    LarryC, You're starting to speak the language. Regarding some of your points: b) The gap you speak of is very critical. Say for a minute you properly designed an ejector and ended up with a gap for some given motive pressure, built it, and you produced some operating condition with it...

    Venturi Vaccum Pump

    Larry and Memepe, I know what you're both after. The first part of Memepe's question is about simple motive nozzle design, and any gas dynamics text book should have the solution. Unfortunately once you start talking about the relationship between the motive nozzle and a venturi (entrained...

    Venturi Vaccum Pump

    I spent a few years doing these calculations. I will post back tonight with the equation. Any gas flow textbook would have it.
