The velocity profile of an incompressible laminar boundary layer over a flat plate developing under constant pressure is given by $\frac{u(y)}{U_{\infty}}=\frac{3 y}{2 \delta}-\frac{1}{2}\left(\frac{y}{\delta}\right)^{3}$. The freestream velocity $U_{\infty}=10 \mathrm{~m} / \mathrm{s}$ and the dynamic viscosity of the fluid $\mu=1.8 \times 10^{-5} \frac{\mathrm{kg}}{\mathrm{ms}}$. At a streamwise station where the boundary layer thickness $\delta=5 \mathrm{~mm}$, the wall shear stress is ___________$\times 10^{-3} P a$
