Velocity potential of a subsonic compressible flow is \[\phi(x,y) = V_{\infty}x + \frac{5}{\sqrt{1 – M_{\infty}^{2}}}e^{-2\pi\sqrt{1-M_{\infty}^{2}}y}sin2\pi x\] Freestream velocity, pressure and temperature are \(200\,m/s\), \(1\,atm\) and \(300\,K\). Find the velocity, pressure and temperature at, \((0.07\,m, 0.07\,m)\).
