Is there a way to model a rectangular pipe in WaterGEMS or WaterCAD?
There is no way of inputting a rectangular pipe directly into WaterGEMS or WaterCAD, though you may be able to enter pipe properties to represent the expected properties of a rectangular pipe.The recommended steps would be as follows. First, for the diameter, you will want to enter a value that will be representative of the cross-sectional area of the rectangular pipe. Find the cross-sectional area of the rectangular pipe and calculate when the diameter of a circular pipe would be with the same cross-sectional area. This way, thevelocity values calculated in WaterGEMS will be similar. In addition, you will want to adjust your roughness coefficients such that the losses are correctly reflected in your model.If you are going to use these values multiple times, it is recommended that you enter these pipes into the Engineering Library. This way, you will only need to figure out this information once.
