To reduce pressure loss due to friction in hoses, what should be attempted?

Using a larger diameter hose or multiple lines is effective in reducing pressure loss due to friction because friction loss in a hose is significantly influenced by the diameter of the hose. A larger diameter allows more water to flow with less resistance, which directly decreases the frictional forces acting on the water as it moves through the hose. This results in improved flow rates and less pressure loss.

When considering multiple lines, the same principle applies. When water is distributed among several hoses, the overall volume of water can be increased while managing friction loss. This is particularly crucial during firefighting scenarios where maximizing water delivery to a nozzle is vital for effective firefighting operations.

In contrast, other approaches mentioned may not effectively address the issue at hand. Using shorter hoses may help reduce some friction loss, but it is not always practical or feasible in all situations. Increasing pump pressure could potentially compensate for pressure loss due to friction, but it doesn’t directly address the root cause of friction losses, which is more effectively managed through hose size and configuration. Minimizing bends in hoses can also assist in reducing friction loss, but the primary method embraced in this context is the diameter and the use of multiple lines, as they have the most significant impact.
