A comparison of the above expression with the experimental findings of 

 Schubauer and Klebanoff shows a somewhat better agreement than the Fediaevsky 

 relations. 



The integral of the shearing-stress distribution will now be studied 

 by integrating the analytic relations just described for the shearing-stress 

 distribution and by analyzing the test data of Schubauer and Klebanoff. Let

By elementary integration the following expressions are derived: For the 

 Fediaevsky 3-condition polynomial, Equation [60],

for the Fediaevsky 5 _ condition polynomial, Equation [6l], 



I = 0.60 + 0.15a [65]

Significant results are obtained from the data of Schubauer and 

 Klebanoff when the integral of the shearing-stress distribution is non- 

 dimensionallzed as follows
