Abstract: The boundary layer conservation of mass, momentum, and energy equations are numerically solved. The inviscid pressure distribution is also numerically determined in order to specify the boundary conditions along the outer edge of the boundary layer. Finally, the Preston-tube pressure measurements are correlated to the corresponding theoretical skin friction coefficient values by means of a least-squares technique.
