  in the present investigation of the flow of air in a thin laminar
boundary layer on a flat plate, the crocco method has been used to solve
the simultaneous differential equations of momentum and energy involved
in such flow .  the crocco method was used because it gave accurate
results for arbitrary prandtl number near unity .  the prandtl number
was taken at 0.75, the specific heat was held constant, and the
sutherland law of viscosity-temperature variation was assumed to
represent the viscosity data starting with an initial ambient
temperature of -67.6 f .  the main results presented here are the skinfriction
and heat-transfer coefficients as functions of reynolds number,
mach number, and wall-to-free-stream temperature ratio .  variations of
shear, velocity, temperature, and mach number across the boundary layer
are included .  the crocco method is discussed in detail .
