In-line pumping, involving 3.5" hose, results in which of the following?

In-line pumping with 3.5" hose significantly increases friction loss due to its larger diameter and associated flow characteristics. This setup often requires a longer stretch from the rig to the hydrant because the larger hose can be less flexible and more cumbersome, necessitating adjustments in routing. As firefighters work to optimize their operations on scene, they may find that the logistics of moving and deploying 3.5" hose effectively can alter the initial distances they need to cover to connect to water sources.

While a more efficient water flow is generally associated with larger hose diameters, the context of "in-line pumping" suggests a focus on operational strategy rather than purely on flow efficiency. Therefore, understanding that in-line pumping can often lead to longer stretches when pulling equipment and maneuvering is crucial for effective on-scene performance analysis and planning.
