$3\mathrm{.}12$ Consider the flow over a semi$-$infinite body as discussed in Section $3\mathrm{.}11.$ If

$V_{}$ is the velocity of the uniform stream, and the stagnation point is $1$ ft

upstream of the source:

a$.$ Draw the resulting semi$-$infinite body to scale on graph paper.

b$.$ Plot the pressure coefficient distribution over the body; that is$,$ plot $C_p$

versus distance along the centerline of the body.
