the proper flow velocity. A flow that’s too slow results in sluggish system performance, while a flow that’s too high causes excessive pressure drops, system damage, and leaks. Use the Flow Capacity Nomogram in Section E to determine the proper hose I.D. for your appliion’s flow rate requirements. Temperature When specifying hose, there

Guideline for Flow and Pressure Testing of Hydrants

3.1.1 A uniform rating of hydrants is achieved by measuring the flow rate of water at a specified residual pressure. A residual pressure of 1.4 bar (20 psi) is generally recommended to be retained at hydrants when delivering fire flows. 3.1.2 Hydrants having a static pressure of less than 2.8 bar (40 psi) should be rated at one-half of the static

Driver Operator Manual Chapter 3 - Fireground Hydraulics

• Flow Pressure: Pressure created by the rate of flow or velocity of water coming from a discharge opening (measured using a pitot gauge). • Force: A measurement of weight that is expressed in pounds. • Friction Loss: Loss of pressure created by the turbulence of water moving against the interior walls of fire hose or appliances.

Hose Selection CHART 1. Hose Flow Rate vs. Pressure Drop

Hose Length Chart 1 gives the pressure drop in different-sized hoses based on hoses of 100-foot length, and is based on water as the material conveyed. For hoses of a different length, these values must be corrected. For example, a 100-foot length of 1/2" hose causes a pressure drop of 100 lbs./in.2 at a flow rate of 10 gal./min. If the hose in

Fluid specifiion: Specific gravity = 0.85; Viscosity = v = 20 centistokes (C.S.), (20 C.S. = 97 S.S.U.) Pressure drop values listed are typical of many petroleum based hydraulic oils at approximately +100ºF

High Rise Fire-fighting : Flow rates

Firefighters must remeer that 45mm hose can cause serious flow restriction. Use of 51mm Hose will have a lesser effect but it will still impact on flow rates, especially if two or three lengths of hose are required. 70mm (nominally 64mm) hose has a minimal impact on flow rates BUT is extremely difficult to handle and advance within buildings.
