138 Nomography of Discontinuous Motion of a Liquid. 



Fig. 1 was drawn in this way for the case p = l, a =60°, 

 £=26°-3, #=145°-6, ?=0"4, r=0*265. 



As a further illustration of the use of the nomograms, the 

 curves on fig. 8 have been drawn for the perpendicular

incidence of a jet on a plate of the same width. Abscissae 

 are distances of middle of plate from middle of jet. Angles 

 of splash are given by the curves marked ft, 180-/3', using 

 the vertical scale on the left of the diagram. The curve b 

 gives by its distances from the top and bottom of the figure 

 {on the right-hand scale) the parts into which the jet is 

 divided by the plate. Curve r gives in the same way the 

 ratio in which the plate is divided by the point at which 

 the stream divides.
