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?  

  • Thank you Akshaya. The network model is very difficult to show you. It's very complex. Instead I'll send you the site where i'm working in a picture.I need to connect the UG (underground tank) tank to the tank above the building. I have marked them in black circles. So at the bottom of the building can we provide a vertical pipe?

    The basic thing is can we design a vertical Pipe ? :)

  • ADR,

    If you are really after modeling a vertical pipe then Yes we can model a vertical pipe.

    Let's say you have:

    o1-------------o2-----------o3-------------o4

    o1 elevation = 0ft
    o2 elevation = 10ft
    o3 elevation = 20ft
    o4 elevation = 30ft

    o1 to o2 pipe length =10ft
    o2 to o3 pipe length =10ft
    o3 to o4 pipe length =10ft

    Please note, hydraulic result will not change no matter how to draw a pipe or node. Your result will remain the same if put all nodes (o1, o2, o3, o4) just on top of each other or you draw  them in square or in circle or draw however you like. The hydraulic result will remain the same.

    If you agree with what I said then Yes you can very easily model a vertical pipe. Now it's up to you how you want to draw your pipes in the drawing.  

    With the information like above, if you run the model, you will get the result as if the pipes are vertical in the real world.

  • Thank you for the instructions.

    I have a small doubt. See in real world at the bottom of the building a bend upwards is provided 90degrees. here as you old if o2 has elevation 10 ft and o3 has elevation 20 ft. I think the pipe would not bend excatly 90 degrees but in rising gradient type from 20 ft to 30 ft. My main problem is that. :( Please give me an incentive to this issue

  • ADR,

    If you build your model like below and run it. And then you put all the nodes into one location and run it, your result will be the same.

    Regarding your 'T' section, could you please draw and illustrate your problem? 



  • ADR -  I think I understand what you are getting at.  As a solution could you put a pipe at that elbow, assign it an equivalent length for the 90 and set it at the elevation of where that 90 is located at.  Then put a label on it indicating that the is the 90.   That way you will get the effects of the 90.
