Which Canal Discharges More? Faster Flow at the Surface
Comparing the outflow of two channel schemes
A short, faint red-chalk page comparing canal schemes, with zigzag profile sketches. Leonardo asks bluntly which canal pours out more. An analogous figure carries the note (41) that for this reason the water moves more at the surface than at the bottom.

Which canal pours out more?
A question set against the channel diagrams: which canal discharges the greater quantity of water?
The current runs faster at the surface
An analogous figure notes (41) that for this reason the water moves more at the surface than at the bottom.
