Nozzle Tip Relationship to Hose Diameter Rule - Firehouse
22.03.2010· A large nozzle results in a large flow of water and a large flow of water produces large friction loss. With a long hose stretch and a large flow of water, the nozzle pressure weak because of excessive friction loss. In such case, an increase of nozzle pressure requires the use of a smaller nozzle, assuming engine pressure, hose diameter and length of stretch remain constant.

LDH Supply Hose - Large Diameter Industrial Hose | Rawhide
LDH fire hose is big-flow, low-pressure hose, which is both its defining feature and the reason for its popularity. Friction loss in large diameter fire hoses is entirely dependent upon flow, not pressure, so the more capacity (GPM) a hose can carry, the less force (PSI) is needed for the delivery.
Water nozzles and efficiency - Super Soaker Central
11.11.2008· Large nozzles coined with high pressure will create high flow. Similarly, large nozzles with moderate pressure will create high flow. However, small nozzles with high pressure still will have relatively low flow. The equation uses the square root of the pressure, so pressure obviously is less important than nozzle diameter.
