The coefficients p can be determined independently from a(x) in the 

 boundary condition, while a(x) should satisfy an integral equation of the 

 Volterra type of the second kind. The solution of this integral equation 

 never presents a singular behavior. Numerical results for the pressure 

 distribution on a body with semicircular cross section are compared with 



measurements as well as the results of the lowest order approximation and

 those by the strip theory. Fairly good agreement with measured results 



is obtained by the present calculation as shown in Figures 9 and 10, while
