$8\mathrm{.}17$ Find the position $(x,y)$ on the upper surface of the half$-$body in Fig. $8\mathrm{.}5$a for which the

local velocity equals the uniform stream velocity. What should the pressure be at this point?

Fig. $8\mathrm{.}6$ Superposition of a source

plus a uniform stream forms a

Rankine half$-$body.
