### Pressure drag from total drag force on a sphere Formula

Pressure drag force = pi*Viscosity of Fluid*Diameter of Sphere*Flow Velocity
Pdragforce = pi*μ*d*V

## What is pressure drag?

Pressure drag is caused by the air particles being more compressed (pushed together) on the front-facing surfaces and more spaced out on the back surfaces. This is caused when the layers of air separate away from the surface and begin to swirl – this is called turbulent flow.

## What is difference between friction drag and pressure drag?

Skin friction drag is the drag between surface and water. Pressure drag is the resistance generated due to differential pressure along the swimmer body.
