What is the formula for calculating the total pressure loss in a flexible hose?

The formula for calculating the total pressure loss in a flexible hose involves understanding the relationship between the length of the hose, its diameter, and the flow rate of the fluid. The correct formulation accounts for how these factors interplay to affect pressure loss.

In this context, the pressure loss being proportional to the length of the line provides insight into the concept that longer hoses will inherently present more resistance to flow, leading to greater pressure loss. Similarly, while the diameter of the hose is part of this relationship, it inversely affects the pressure loss; a larger diameter typically reduces pressure loss. The flow rate also plays a crucial role, as higher flow rates tend to increase turbulence and friction, thereby increasing pressure loss.

Thus, the formula captures the direct relationship of pressure loss being associated with the line length, while also factoring in the diameter and flow rate, making it a comprehensive representation of how these variables interact in the hydraulic system.
