For which angle θ (between tangential pressure and freestream) does maximum coefficient of pressure exist for a blunt body?

For which angle θ (between tangential pressure and freestream) does maximum coefficient of pressure exist for a blunt body? Correct Answer θ = π/2

For a blunt body, the coefficient of pressure is maximum at π/2. This result is derived from Newtonian theory according to which the coefficient of pressure is related to θ by: Cp = 2sin2 θ For sin π/2, which is the stagnation point, we get maximum value of coefficient of pressure.
