Exploring Fluid Friction Applications

What is fluid friction and how does it differ from solid friction?

• Fluid friction is the resistance encountered when a fluid flows over a surface, differing from solid friction, which occurs between solid surfaces in contact.

• Fluid friction only occurs in gases, while solid friction occurs in liquids.

• Solid friction is always greater than fluid friction in any scenario.

• Fluid friction is the same as air resistance and has no relation to surfaces.
