808 Discontinuous Flow of Liquid past a Wedge. 



The graph DG/DH shows the shrinking o£ the pocket of 

 dead water to nothing as the Bobyleff case is approached, 

 when the breadths of the planes are equal. The actual 



Fiff. 3. 



length of the pocket passes through a maximum, as indicated 

 on the graph marked DG/DB. The approach on the point 

 of division of the stream to the corner is shown by DC'/CB, 

 which is plotted on a tenfold scale. Q'/Q is the ratio of the 

 velocity along the boundary of the pocket to that along 

 the ultimate free stream-lines.
