Problem
Is there a way to model a rectangular pipe in WaterGEMS, WaterCAD or HAMMER?
Solution
WaterGEMS, WaterCAD and HAMMER support and assume pipes have a circular shape.
To model a non-circular pipe shape, first enter a diameter value that will be representative of the cross-sectional area of the non-circular pipe. Find the cross-sectional area of the rectangular pipe for example and calculate when the diameter of a circular pipe would be with the same cross-sectional area. This way, the calculated velocity will be similar. In addition, you will want to adjust your roughness coefficients such that the losses are equivalent.
Note: pipes are assumed to always be pressurized in the water products.
