Problem
Two identical open containers are filled to the same depth with water. Container X has a pinhole of radius 1mm near the base, while Container Y has a pinhole of radius 3mm at the same vertical location. Neglecting viscosity, which statement best describes the initial exit speeds of the water jets?
(a) The speed is greater for Container Y because a larger opening allows more water to flow.
(b) The speeds are equal because they depend only on the depth below the surface.
(c) The speed is greater for Container X because forcing water through a smaller opening increases its velocity.
(d) The speeds cannot be predicted without knowing the cross-sectional area of each container.
