  / g 0 V02 q 10Here, Ps is the pressure on the spherical surface, P is the pressure at infinity,  is the density ofthe fluid, g0 is the gravitational constant, V0 is the air flow velocity of the wind tunnel and q isthe dynamic pressure. The difference between the high pressure in the front stagnation regionand the low pressure in the rear separated region causes a large drag contribution called pressuredrag. This is added to the integrated shear stress or friction drag of the body, which it oftenexceeds. The relative contributions of the friction drag and the pressure drag depend on thebody’s shape, especially its thickness
