SkinFrictionCoeff:

deprecated

--------------------------------------------------------------------------
   Computes skin friction.

   This uses the function cF = 0.075/(f*rE^0.2)
   where f = sqrt(M) for M >= 1 and 1 for M < 1.
   To prevent a singularity at M = 0 it fits a linear function that
   has the same slope and value as cF(m0) at m0.
   There is a slight discontinuity at M = 1 due to f.

   Type SkinFrictionCoeff for a demo.
