Coefficient of pressure at stagnation point

http://web.mit.edu/13.021/13021_2003/Lifting%20surfaces/lectureB.htm Using Bernoulli's equation, the pressure coefficient can be further simplified for potential flows (inviscid, and steady): where u is the flow speed at the point at which pressure coefficient is being evaluated, and Ma is the Mach number: the flow speed is negligible in comparison with the speed of sound. For a case of an incompressible but viscous fluid, this represents the profile pressure coefficient, since it is …
