Homework Statement
My main problem here is that I do not understand what they are asking. What is the wall shear stress? Do they mean the stress at the "floor" (or whatever you want to call it)?
If so, I am assuming I use Newton's Law of Viscosity [itex]\tau=\mu\frac{du}{dy}[/itex] since this is 1-dimensional flow.
Would the wall shear stress [itex]\tau_w[/itex] be given by
[tex]\tau_w=\int_{y=0}^\delta \tau(y)\, dy[/tex]
and then the problem reduces to finding an expression for [itex]\tau(y)[/itex]
Or am I way off here? thanks
