I would like to know the formula used in the tutorial on the page 32 of the French version or the page 33 of the English version; to have the result of consumption rate of the agricultural demand(request) equals in 90. Otherwise (differently) say, what is the formula allowing to estimate the reteof consumption? Thank you.

The 90% value used in the tutorial is an example value - it is not based on data. To obtain that information, you would have to have a good sense of how much water agriculture withdraws, and how much water is returned to the river. For example, if I had 100 MCM coming in, and 15 MCM returning to the river:
15/100 = 15% return, so 85% consumption. But it would be based on data, or in the absence of that, estimations and assumptions.
