$(10$pts$)$ Solve for the section drag coefficient

for steady, incompressible flow past a cylinder.

The wake's velocity profile is symmetric and can

be approximated by the equation below. Hint:

Since the wake is symmetric, you only need to

solve one$-$half of the profile and then double it$.$

$u(y)=V_{}(\frac{y}{2D}{)}^{\frac{3}{2}}$

$V_{}$
