KYPipe / EpaNet Gravity Main Modelling

[meghna77]

Hello to you all,

I have been using KYPipe for hydrualic analysis of gravity systems. I am analysing a gravity main (50.44km in length), starting off with a 600mm diameter and narrowing down to 500mm towards the end of the line. Along the length of the line, the pipeline diverges into 3 separate pipelines flowing to reservoirs in different areas. I have managed to analyze the system in KYPipe using a Demand-driven analysis.

However, I would like to analyze this system using Pressure-driven analysis, whereby I can set the flow capacity at the source of the pipe and let it flow freely into all 3 pipes, without putting any demand constraints. This would help me verify the flows in each pipe, regardless of the demand being fixed.

I am also new to using Epanet and I am still struggling to model this scenario in that.

Please do let me know if any one of you has come across this. Any help would be much appreciated!

Thanks!

try posting in the Water Treatment and Distribution forum. EPAnet followers are usually watching that forum.

I hate Windowz 8!!!!

EPANet and KYPipe are for pressurized not gravity systems. You didn't mention if you are modeling stormwater, wastewater or a combined system. Try a one of these links for modeling gravity systems:

Also, if you have Civil 3D, you could use SSA, which comes with the Civil 3D software package, to model both stormwater and wastewater systems.
