Consider a laminar flow in the x-direction between two infinite parallel plates (Couette flow). The lower plate is stationary and the upper plate is moving with a velocity of $1 \: cm/s$  in the x-direction. The distance between the plates is $5 \: mm$ and the dynamic viscosity of the fluid is $0.01 \: N-s/m^2$. If the shear stress on the lower plate is zero, the pressure gradient, $\dfrac {\partial p}{\partial x}$, (in $N/m^2$ per $m$, round off to $1$ decimal place) is _________
