WaterGEMS- Hands on learning question

Question

Hi 
 I am studying the hands- on learning document : Steady State Calibration of Field Measurements (metric). 
 My question is: 
 1-in the last page of the document it shows adjusted demands which I don't know how they did calculated? 
 2- Also, in the second capture it shows the pressure as Kpa and corresponding HGL-m. please let me know how can they convert Kpa to HGL metric as they seem are incorrect! 
 Thanks 
 
 Hamid

There is a section on "Adjusting Demands" on pages 191-193. This will explain where the results from that table come from. 
 
As for the "Static Condition" table, that is field data that was collected. It is not data the program computed. The psi is the pressure collected at the nodes in the field. The HGL is the water surface at these nodes. See the explanation above the table on page 184.

Hamid, 
 
This wiki solution also explains a little bit more about how the adjusted demand is calculated and why it may not match the original demand. Based on your post I thought it may also be of interest to you for future questions.
