As seen in Figure 5> plots of u/U against H yield single curves for each value 

 of y/0.

For purposes of mathematical analysis it is found very useful to 

 consider a general-power -law distribution for the velocity profiles of the 

 form

Using this power law Pretsch derived the following relations between the 

 boundary-layer parameters

(n+l)(2n+l) ~ H(H+1) 



H = 2n + 1
