What is the friction loss in 450 ft of 2 1/2" hose when flowing 250 GPM?

To determine the friction loss in 450 feet of 2 1/2" hose when flowing 250 GPM, we need to apply the formula for calculating friction loss in a hose. The friction loss in hoses is typically estimated using the Hazen-Williams formula or a standard friction loss chart.

In this scenario, when flowing 250 GPM through a 2 1/2" hose, the friction loss is primarily influenced by the diameter of the hose, the length of the hose, and the flow rate. For 2 1/2" hose, at a flow rate of 250 GPM over a length of 450 feet, the calculated friction loss is found to be approximately 56 psi.

This value is derived from friction loss tables that provide the loss based on flow rates and hose dimensions, confirming the loss as being significant at this specific configuration. Therefore, 56 psi is identified as an accurate friction loss for the given parameters, reflecting the pressure required to overcome the resistance caused by the length and diameter of the hose when water passes through it at the specified flow rate.
