Lift on the Disk

Finally, we briefly return to the condition (5 171) for validity of the uniform blowing assumption. If we substitute P = fi(Re), this condition becomes 

Likewise, with ft = 6 and d2 given by (5-226), the condition (5-171) again becomes 

we expect that the uniform blowing approximation should be valid, provided
