a simplified approximate theory is presented by means of which the
laminar boundary layer over an insulated two-dimensional surface may be
calculated, a linear velocity profile being assumed, and an estimate
made of its effect in changing the pressure distribution over the profile
upon which the boundary layer is formed . skin friction is also
determined . comparisons of results from this theory are made with experimental
results at a mach number of 6.86 and a reynolds number of
