Friction factor for water

WebThe friction factor caused by the internal wall roughness has a greater effect on the friction factor in small pipe sizes. This means that a small diameter pipe will approach … WebStatic friction prevents sliding. Static friction is the force holding an object in place on an incline, such as the cheese in Figure 1. The friction force points against the direction that the object would slide without friction. Static friction keeps gravity from pulling the cheese down the incline.
