Objectives

The purpose of this Tutorial is to train the trainees how to: -Construct a new WaterCad model, -Manually enter all the required data in the model, -Run the model and clear the model errors (if any), -Investigate the model results, -Carryout sensitivity analysis.


C = 100 (all pipes);

Given the water distribution system shown in the below Figure, it is requested to construct a WaterCad model and to run the model assuming all pipes roughness of C=100 which corresponds to 10-years old Cast Iron.

Changing Labels and Node Changing Labels and Node

Numbering in Numbering in WaterCadWaterCad WaterCad uses automatic sequential numbering. If user

deleted 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:

Tools Options Labeling

Change the next number you

like WaterCad to begin with.
