Propeller Drag due to Form Drag of Propeller with Locked Shaft Formula

What causes Skin Friction?

The Skin Friction drag is caused by the viscosity of fluids and is developed from laminar drag to turbulent drag as a fluid moves on the surface of an object. Skin friction drag is generally expressed in terms of the Reynolds number, which is the ratio between inertial force and viscous force.
