Canal Barrier with Three Openings a, b, c
Which of equal outlets discharges the most water - three openings, then two
In red chalk and drawn upside-down, this leaf shows a barrier thrown across a canal with three openings a, b and c set between the banks (argine) and the bed (fondo), beside ruled water-lines. The note asks which of these equal holes will pour out the most water. A second, smaller study repeats the question for two outlet holes.

Which of three equal openings a, b, c pours most
A barrier across the canal carries three openings a, b and c between the two banks and the bed. The question is which of these equal holes will discharge the greatest quantity of water.
Which of two holes pours more
A further study of water issuing from two holes repeats the same enquiry, asking which of the two discharges the more water.
