Channel on a Slope and Four Equal Outlet Holes
Water runs faster at a channel's bed than at its surface; which of four equal holes pours most
Drawn inverted in red chalk, this leaf sets down two water problems beside a channel profile and a serpentine flow-line. The first note holds that water descending a slope of equal inclination moves more strongly along the bed of the channel than at its surface. The second asks, given four outlet holes a, b, c, d of equal width, which of them will pour out the most water.

Water flows faster at the bottom of the channel
The note reasons that water running down a fall of equal slope moves more strongly at the bed of the channel than at its surface. It is set beside a drawn profile of a channel.
Which of four equal holes a, b, c, d pours most
With four outlet holes labelled a, b, c and d shown of equal width, the question is posed as to which of them will discharge the greatest quantity of water.
