2014/06/02· City Against Fire,” published in 1892.8 Freeman had done the fundamental work on water flow through hose and nozzles, so he was able to pin down the definition of a standard fire stream to one with a discharge of 250 gpm (946 L/min) at 40

Hose Size Selection - Flow Capacities at Recommended Flow Velocities. The nomogram below can be used to determine the hose I.D. (or dash size) that you will need. Use a straight edge to connect the flow rate that your system requires with the recommended velocity range for your appliion. The intersection of these two points is the required

2018/02/02· Contrary to what I always believed hose diameter does not affect flow rate just pressure. So let''s compare a 1/2" hose to a 3/4" hose connected to a 7gpm pump. A 1/2" hose would generate 11.5FPS and a 3/4" hose is 5fps. Each

Hose sizing is based on inside diameter, so a one inch hose is truly one inch making it much easier to calculate fluid velocity for a given flow rate. Sin #3 - Sizing case drain lines based on volumetric efficiencies of a new piston pump

2011/10/19· Hose and tubing need to be the right diameter, length, smoothness and shape to handle the demands of the pressurized hydraulic flow. Undersized hose or tube can cause turbulent flow and excessive heat buildup. Over-sized hose or tube can add cost, size and weight to a system and decrease the rate of flow. To understand what “right-sizing

Hose Flow Capacities Pressure Drop Pressure drop in psi (pounds per square inch) per 10 feet of hose (smooth bore) without fittings. Fluid specifiion: Specific gravity = 0.85; Viscosity = v = 20 centistokes (C.S.), (20 C.S. = 97
