To calculate the location of the center of pressure for an airfoil section in low-speed, incompressible flow, we can use the following formula:
Where:-
is the location of the center of pressure-
is the lift coefficient-
is the center of pressure coefficient-
is the chord lengthGiven:-
-
-
(assuming the chord length is 1 for simplicity)Substituting the given values into the formula:
Therefore, the location of the center of pressure is approximately 0.98 chord lengths from the leading edge.
