The skin friction coefficient, 
, is defined by:
Where 
is the local wall shear stress, 
is the fluid density and 
is the free-stream velocity (usually taken ouside of the boundary layer or at the inlet).
It is related to the momentum thickness as follows: C_f = 2(d theta)/ (d x)
Someone should add some correlations and references for them here
