    Definining pressure on line, N/mm?

    Ok, Ansys defines force per area for pressure on a line. It makes sense if I think of the cross section as an extrusion, I got confused.

    Definining pressure on line, N/mm?

    Ok, This is the tutorial I'm following now; http://www.ndsu.edu/me/images/Kallmeyer/477/Pressure%20Vessel%20Example.pdf I will try modeling in 3d after that, probably more accurate. I have only worked on 2d models in Ansys, so it should be interesting. Thanks

    Definining pressure on line, N/mm?

    Hi I'm new to Ansys. I'm working on a cross section of a pressure vessel. I have the dimensions modeled as a half cross section of the vessel. But when adding the pressure "on line" on the inner line of the cross section of the vessel defined as N/mm, N/length, the units is kind of strange to...

    Finding correct pumps

    Tenpenny: Right now the weight is the highest priority, so that the structure people can do their thing. Still, finding an exact pump is certainly not wrong. The document is great, but it doesn't seem to cover the larger ones? It seems that when you reach the 500kw mark the googling market...

    Finding correct pumps

    Right. And assuming an efficiency for the thermal oil is probably even more difficult because of the unknown viscosity in the various temps? I will just have see what kind of answer I get.

    Finding correct pumps

    Thanks Artisi, i have found many of your posts helpful. I just did what you said(like a pro businessman), if this works I will buy a cigar!

    Finding correct pumps

    Hi! I’m trying to find the right pumps for a heating medium and cooling medium system. We have the required flow rates, temp variations and power needed for the pumps, but we don't have the actual pump weights and a specific pump product from a supplier. Centrifugal Pump 1 m³/h 1600 kW 430...

    Operational risks of operating centrifugal pumps in series

    I kinda have the same question as Lan85. I was told that if the mass-flow variations is too high a parallel system is preferred. (centrifugal pumps) Also when it comes to redundancy. If one pump fails in a parallel system it should not be a great problem. In series, if one pump fails, the whole...

    Filtration of hot oil heating medium

    Thanks for the help. Gotta be honest, I didn't even know what i was asking when I wrote the thread, but now I kinda know what i'm looking at and have some good sources. I found the hot oil strainer to be pretty large, over 2m tall and 1m wide with 20" pipe connections. I will contact a...

    Filtration of hot oil heating medium

    Hi! I'm a mechanical engineering student working on a natural gas production plant (Ormen Lange, Norway). The system we are working on is the heating medium part, containing pumps, heat exchangers, furnace, filters and expansion tanks. We just started and so far we have a pretty good idea of...
