Nomogram for q, « =90°. 



Fig. 5 shows the nomogram. It is drawn with the sign of 

 the function reversed, so that the value of r is the distance 

 measured downwards from the point a to the chord joining 



St*. 



The coordinates of a point on the free surface of the 

 liquid are expressed as functions of the variable parameter u 

 (equation 26, loc. cit.). Hence, by use of the modified 

 analysis, we get them in terms of the inclination of the 

 tangent at the point, and we find once more that the equa- 

 tions can be written in the nomographic form. Let the 

 origin be at the right-hand edge of the strip, then 6 runs 

 from to /3 along the free surface which starts from the 

 origin, and from j3 to a. along the other side of this jet and 

 the right-hand side of the incident jet.
