Chapter 1, Problem 1.3P

Consider an infinitely thin flat plate of chord c at an angle of attack $\alpha$ in a supersonic flow. The pressures on the upper and lower surfaces are different but constant over each surface; that is, $p_u\left(s\right)=c_1$ and $p_l\left(s\right)=c_2$, where $c_1$ and $c_2$ are constants and $c_2>c_1$. Ignoring the shear stress, calculate the location of the center of pressure.
