Hello there,
I am an engineering tech student and am working on a project which involves creating a water distribution model for a small town in WaterCAD V8i and doing a basic pressure/flow analysis on it. I've created the model with the appropriate data however when I run the analysis I am getting some strange results. The first thing I notice is that when I run the analysis and check the graph of my demands it showing that there is a flow demanded which follows my demand pattern however its saying that there is no flow supplied. I have a feeling that maybe I am inputting incorrect demands. I am taking the average daily demand of 340 L/Day per person and then muliplying that by a population of 2278 people and then dividing it by the 34 evenly spaced nodes to get a total of 22,780 Litres a day as my base demand that showing for each node. Does my base demand sound like its somewhere in the ballpark of where it should be? Im running an EPS and pairing this base demand with a common hydraulic pattern in the demand control center. The other problem I'm noticing is that when I run the analysis is that my flows are almost non existent however my nodes are showing that I have pressure at the ranges they should be at. Could the problem be with my pump curves perhaps? Any ideas what I might be doing wrong here? Thanks for any help!
