What is the hose coefficient for 1 3/4 inch hose?

• A. 3
• B. 1
• C. 0.5
• D. 2

Answer: (B)

The concept being tested is how friction loss is scaled for different hose sizes using a hose coefficient. This coefficient is a fixed value used in standard friction-loss calculations to reflect the hose’s diameter and roughness characteristics. For a 1 3/4 inch handline, the established coefficient in training tables is 1. This gives you a consistent baseline: once you know the flow and the length, you apply the table’s method with that coefficient to estimate the friction loss. The other numbers correspond to different hose sizes, not to 1 3/4 inch hose, so they don’t apply here.
