What is pressure coefficient?

The pressure coefficient is the dimensionless pressure used in aerodynamics. It is obtained as the ratio of the difference between surface pressure & free-stream pressure to the free stream dynamic pressure.

What is the highest value of pressure coefficient in an incompressible flow?

The highest value of the pressure coefficient is equal to one at the stagnation point in an incompressible flow. For compressible flow pressure coefficient at the stagnation point is always greater than one.
