Which method would be best to ensure low friction loss in hoses?

Avoiding sharp bends in hoses is critical for ensuring low friction loss. When hoses are bent sharply, the water must navigate through a tighter pathway, which disrupts the smooth flow and increases resistance. This increased turbulence leads to higher friction losses, resulting in a decrease in water pressure and flow rate at the nozzle. By maintaining gentle curves and avoiding kinks in the hoses, the flow remains more streamlined, thereby reducing friction losses and optimizing the efficiency of the water delivery system.

In contrast, longer hoses would actually increase friction loss due to the greater distance the water must travel. Employing smaller diameter hoses also contributes to higher friction loss since they create more resistance for the water flow. Utilizing older nozzles might not necessarily address the issue of friction loss effectively, as nozzle design impacts flow characteristics, and older models may not be as efficient as newer designs. Therefore, avoiding sharp bends is the most effective way to minimize friction loss in hose systems.
