Thank you very much

[@theexcellenttechshorts]

Please tell me how to create that demand shapefile in qgis or arcgis

How can I calibrate the watercad model have any steps or vedioes recommend to follow them please

@@bentleyopenflows When exporting the Darwin calibration after matching the actual behavior of my water distribution system, the demand and C appear in the flexible table as the input values not as an adjustment demand and roughness although I run the calibration a scenario, why? I need to update the demand and roughness according to adjustment values and begin analysis. How can I do this please?

new subdivision of 36 homes is being constructed in a new area of town. The water supply network for the subdivision needs to be designed to meet the peak demand of 61.2 l/s (1.7 l/s per home × 36 homes). All junction nodes are 192 m in elevation. All pipes are ductile iron (C = 130). Use the Hazen-William's equation to determine the friction losses in the pipe. Tell me how to do in water gems software please sir

I would recommend reviewing the WaterGEMS training course which you can find as a playlist on the homepage of this RUclips channel. If this is an academic assignment/homework, you may need to consult with your professor regarding constraints. There does not seem to be enough information provided in your post. For example you would need to know how many pipes there are, their length and connectivity, and where the water source is (tank? Connection to existing system? Pumped well?)

Pls share the data file used for demonstration

What will be the value of k factor that is to be given for 60-40 distribution?

[@prospermaaweh9203]

I would assume the k factor values have to sum up to 1. Hence if a value of 0.6 (60) is inputted for the starting point, the software automatically assigns 0.4 (40) to the end.
