The wall shear stress, <math>\tau_w</math>, is given by:

:<math>\tau_w = \mu \left(\frac{\partial u}{\partial y} \right)_{y=0}</math>

Where <math>\mu</math> is the [[Dynamic viscosity|dynamic viscosity]], <math>u</math> is the flow velocity parallell to the wall and <math>y</math> is the distance to the wall.
