Fitting friction loss
WebFriction Loss. Friction is the resistance required for moving a body through an external surface. But the friction loss is connected to the flow of liquid through a pipe. In other sense, it is a kind of energy loss because of the friction inside the tube. It is intimately related to the velocity and viscosity of the fluid.
