text: This information can be used to show that the pressure coefficient  at a stagnation point is unity (positive one):
  where:
  : is pressure coefficient
  : is static pressure at the point at which pressure coefficient is being evaluated
  : is static pressure at points remote from the body (freestream static pressure)
  : is dynamic pressure at points remote from the body (freestream dynamic pressure)
  Stagnation pressure minus freestream static pressure is equal to freestream dynamic pressure; therefore the pressure coefficient  at stagnation points is +1.
