Pipe Network total volume of pipes & structures ?

[cyberflow]

Hi there,

I oftenly do conception for parkings and always need to have the calculated rentention of water volume in the pipe network.

I was asking myself ... is there a way to have that information with Civil 3d ?

Googled the subject and i only found a topic on trench's for the pipes ...

thats interesting. You could try an expression in the pipe labels {length}x{area of pipe} and create a table using it. Totals would still need to be added up thugh

If you are calacalating the volume in pipework would you also need to take into account the volumes in the structures?

If so you need the hydraulic gradients etc this is why most would use a 3rd party application to model the volumes of water. Some pipework would have low flows and some high flows dependant on the impermiable area so you would also need to take this into account. May be easier to dump into Windes or SSA.

As for a rough volume with total, Quantity take off would be one way forward but wont give you the pipe referances only lengths & volumes. A network table would do wwhat you wamt with no running total but you will as stated need a calcalation. The Volume could be added as a custom context if needed otherwise it would be something like ({2D Length - To Inside Edges} * (pi*({Inner Pipe Diameter}/2))) this would take into account the reduction of the pipework in the structures.

Your radius needs to be squared.
({2D Length - To Inside Edges} * (pi*({Inner Pipe Diameter}/2)({Inner Pipe Diameter}/2)))
