Evaporation from a decoction pot at a rolling boil, litres per hour.
This is a rate and not a fraction of the pull. With a fraction, the
evaporation depends on the pull size, which depends on the evaporation, and
the whole volume waterfall becomes a fixed point that has to be iterated. A
pot at a given vigour evaporates at a roughly fixed rate whatever is in it,
so the rate model is more accurate and isn't circular: e is known before
the pull is sized. 1.5 L/h suits the 8–12 L pot a decoction is usually
boiled in, well under the 3 L/h of a full kettle.
