How does waterCAD calculate the value of Flow Supplied in the reservoir ?.

Hello Alexander,

WaterCAD is a demand driven software, where reservoir supplies the required flow. So the flow out of the reservoir will be equal to the total demand in the system. In below screenshot for initial 0.00 time-step total demand is 2.24 L/s, so flow supplied by the reservoir = total demand at that time-step = 2.24 L/s.

Here is learning resource guide of WaterCAD, for your reference.
