A [x] meter diameter flag pole (cylinder) in air has a Reynolds number of 1×105.  From the figure below, the drag coefficient is approximated as 1.1   Find the drag on the flag pole if it is [y] meters tall.  Use the density of air as 1.2 kg/m3 and viscosity as 1.8×10-5 kg/(m*s). Enter your numerical answer below, without units. Include three digits in your answer and give the numerical answer in N.

Fully-developed steady laminar flow is driven between two parallel plates by a pressure gradient in the x-direction. The upper plate at y=H/2 is stationary and the lower plate at y=-H/2 moves to the right with velocity Uwall.  Assume that v=0 and w=0 everywhere in the flow field and that the flow is fully-developed and steady.  Neglect body forces. To solve this problem, you will use the x-momentum equation.  For the flow described above, mark ALL boundary conditions that are used to find the x-direction velocity profile.
