In regard to small diameter hoses, which statement is correct?

Small diameter hoses indeed experience high friction loss compared to larger hoses. This phenomenon occurs because the smaller the diameter of the hose, the greater the resistance to the flow of water or another fluid. Friction loss is directly related to the length and diameter of the hose; in small diameter hoses, the increased surface area relative to the volume contributes to a significant loss of pressure as water flows through.

Understanding this concept is crucial for firefighters and operators because it affects not only the efficiency of water delivery but also the overall tactics used during fire suppression and emergency situations. When planning operations, awareness of friction loss helps in calculating the necessary pressure and ensuring effective water flow to the nozzle, which is vital for successful firefighting efforts. Thus, recognizing the implications of high friction loss in small diameter hoses allows for better decision-making in various firefighting scenarios.
