By definition ^ m is the maximum value of q, then 



Q m = K,-K 2 (13) 



Therefore 



K i = Q m (,+n) (19) 



Substituting these values in equation 17 



V-'O m (i+n + *)i 



v«o m (r+^n)X 



In order to compute the value of "n", the formula derived on the first as- 

 sumption is arranged in the same form as that which was used to compute the 

 percent deviation. 



Q m (computed)- Q m (observed) t w ™ 



rrv 



^vwm^.su; w m i 



Q m (computed) j 



Substituting the value of Q m found in equation 20 we have

Inasmuch as table 1 shows that the average deviation based on the first as- 

 sumption is 10, high, then 



4n =0 14 

 3 + 4n u 



n = 0.122 



Substituting this value in equation 20 the corrected formula is 



Q m = 0.86 -^ (21) 



Recomputing the values of Q m given in table 1 with the corrected formula the 

 results are shown in table 2<,
