Pipes in water cad v 8i

Hello , I recently surveyed my college pipe network and wanted to make it in water cad and analyse it. I got all the surface elevations , contours etc
MY DOUBT is when we connect a pipe to a tank  to another tank. When there is a vertical downward/upward bend in pipe how to represent it in water cad.

I tried a lot but bend is happening only horizontally. Please help me with it.

  • Hello ADR,

    Pipe lengths are assumed to be horizontal. So, a vertical pipe can be modeled by choosing "true" for "has user defined length", then entering the vertical length. Enter the elevations of the adjacent nodes based on the elevation difference. Profiles will show this pipe's length as horizontal, but the hydraulic results should be accurate.  Let me know if you have any question. 

    So you know, the answer to this question is available in Bentley's online KnowledgeBase, which can be found at the following link: appsnet.bentley.com/.../Default.aspx

    Please search for the kb entry 60960.  You can also find other numberous frequently asked question in our knowledgebase.  Thank you.

  • Honestly I did not go check out the knowledge center and I am sure it is covered but what about at situation where you are modeling a high rise and you wanted to know each floor or top and bottom?

  • Hi nkg2,

    Could you elaborate on what you mean by wanting to "know each floor or top and bottom"?

    The elevations of the nodes at each end of your vertical pipe would be the elevations of the top and bottom (so you can see corresponding accurate pressure reported at each.)

  • Hi Jesse (and sorry ADR for hijacking), in regards to modeling everything is typically in x,y coordinates when drawing it out but in a high rise if you put demand nodes on each floor or top and bottom (whatever the case may be) the nodes would be stacked on top of each other.  Why would someone do this?  Some situations I encounter is fire suppression availability in the worst case scenario or top floor, vacation units versus full time units, businesses, laundry/wash facilities, etc. which would necessitate different demands and conditions on a per floor basis.  That is what I mean.

  • Hi Jesse Dringoli,

    Please could you tell me where to enter those elevation points I did choose the 'true' option .But from there i don't know how to proceed. Please help me. :)

  • If there are bends and no junctions at the vertical section of a pipe. Then ?

    Then you will not be able to report the pressure, HGL, etc at the desired elevations. You'll need to insert a junction at the bend points.

    The elevations are entered in the nodes (such as junctions, hydrants, tanks), not the pipes. At any point along the pipe where you want to report pressure, etc, you will need to insert a junction and enter the elevation. See attached.
