Jets from Tubes: Uniform vs. Non-Uniform Openings
Comparing jets a and b from pipe c, and water through openings of uniform versus varying width.
Red-chalk sketches of pipes throwing out water accompany two questions about jets. Leonardo asks what difference there is between water passed through a hole of uniform width and one of non-uniform width, with water poured from a vessel as the example. Two tubes lettered a b and c raise a further question: whether the water squirted out at a from pipe c is moved by a greater power than the water of pipe b. Further faint red-chalk text is present on the sheet beyond the lines transcribed here.

Uniform versus non-uniform openings
Leonardo asks what difference there is between water passed through a hole of uniform width and one of non-uniform width. Water poured from a vessel serves as the illustration.
Comparing the jets from pipes b and c
Two tubes are lettered a b - c. Leonardo asks whether the water squirted out at a from the pipe c is moved by a greater power than the water of the pipe b.
