What factors affect pressure loss in a hose?

The correct answer focuses on three critical factors that significantly influence pressure loss in a hose: hose inside diameter, hose length, and flow rate.

The inside diameter of the hose is essential because a larger diameter reduces friction and allows water to flow more easily, thus decreasing pressure loss. In contrast, a smaller diameter increases friction and leads to greater pressure loss along the length of the hose.

Hose length also plays a crucial role; the longer the hose, the more friction the water encounters as it moves through it. This friction leads to a greater reduction in pressure. Therefore, longer hoses result in more pressure loss compared to shorter hoses.

Flow rate is the third significant factor affecting pressure loss. A higher flow rate generally leads to increased velocity of water through the hose, resulting in greater friction against the hose walls. This increased friction can cause more substantial pressure loss.

The combination of these three factors provides a comprehensive understanding of how to manage and mitigate pressure loss when using hoses in aquatic pest management and other applications.
