Which is a cause of friction loss in fire hose?

Friction loss in fire hose occurs when water flows through the hose and encounters resistance, which can significantly affect water pressure and flow. One primary cause of friction loss is sharp bends in the hose. When the hose is bent sharply, the water has to change direction quickly, increasing turbulence and resistance. This turbulence creates additional friction between the water and the inner surface of the hose, leading to a greater loss of pressure.

While other factors can influence friction loss, such as the diameter of the hose, the length of the hose, and the speed at which the water flows, the presence of sharp bends is particularly impactful in creating resistance. Understanding how to minimize these bends when laying out hoses can help fire crews maintain better pressure and flow, especially in critical situations.

This emphasis on hose management and minimizing sharp bends in the hose layout is crucial for effective firefighting operations, where every bit of pressure and flow can make a significant difference in achieving a successful outcome.
