What is a potential outcome of not adjusting the pump pressure when the hose length changes?

When hose length changes, it directly affects the dynamics of water flow and pressure within the firefighting system. If the pump pressure is not adjusted accordingly, the ability to maintain an effective pressure for firefighting operations can be compromised.

Longer hoses present increased friction loss, which means that without an adjustment, the pressure at the nozzle could be significantly lower than needed. This reduction in pressure can hinder the effectiveness of the stream, making it difficult to reach and suppress the fire adequately. Thus, the desired outcomes such as effective water delivery and reach are jeopardized, which ultimately impacts the safety and efficiency of firefighting efforts.

In essence, the potential outcome of failing to adjust the pump pressure in response to changes in hose length is a critical shortfall in the delivery of necessary pressure for effective firefighting, which is why this choice is accurate.
