The values in Table Q are presented as an auxiliary plot in Figure 41. Interpolation at the 

 design h/L^ of 0.313 yields the following values of F'jj for relative breaking of 50 and 75 

 percent respectively. 



Relative Breaking of 50 percent (Line B): (Fjj)^ = 4.90 

 Relative Breaking of 75 percent (Line C): (F^)),, = 6.10 



To interpolate to the design H/L^, the distances Aj and A^ are measured from 

 Figure 40. For this example, these are found to be: 



Ai = 0.11 in 

 A 2 = 0.32 in 



The weighting values are then (Equation 50) 



L Ai + Az 



= 0.744 



W = =-^ — 



U Ai + A: 



= 0.256
