C = 100 (all pipes);
Given the water distribution system shown in the belowFigure, it is requested to construct a WaterCad modeland to run the model assuming all pipes roughness ofC=100 which corresponds to 10-years old Cast Iron.

Numbering inNumbering in WaterCadWaterCadWaterCad uses automatic sequential numbering. If userdeleted any element by mistake, WaterCad automatically will
skip the number of the deleted item and start numbering
afterward.
In order to start the automatic numbering from a certain
number you like, do the following:

Change the next number you
like WaterCad to begin with.
