Efflux 



The efflux of a liquid through a slot in the side of a vessel whose contour is a polygon 

 is easily handled, and many cases have been solved. A simple case is shown in Figure 192a; 

 streamlines inside the vessel and a few equipotential curves are shown for the same case but 

 with a narrower slot in Figure 192b. Three other cases are shown in Figure 193. See Tumlirz,^'
