Experiments upon the Contraction of the Liquid Vein: Issuing from an Orifice, and upon the Distribution of the Velocities Within It.

Extracts. Notwithstanding the numerous experiments made since the seventeenth century upon the flow of liquid veins through orifices, there are important matters connected with this phenomenon which still remain undetermined, or so imperfectly known as to give rise to most inexact hypotheses. Until now we have had no experimental results respecting the pressures exerted in the interior of the vein, or upon the velocities of the separate filaments. It was therefore highly desirable that deli...
