In a given size hose, a higher flow rate produces more friction loss. At a given flow rate, the smaller the diameter of the hose, the greater the friction loss. With any combination of flow and diameter, the friction loss is proportional to the distance. Elevation affects water pressure.

1) A watering tank is located 3000' from a pump and pressure tank. A flow rate of 5 gpm is required at the watering tank, and a pressure loss of 10 psi is acceptable. Determine the best size of PVC pipe for the job. For 1" pipe : = 45.9' = 45.9 x 0.433 = 19.9 psi. For 1.25" pipe : = 12.2' = 12.2 x 0.433 = 5.3 psi. Use the 1.25' pipe. Head Loss ...

Proper discharge pressure (45-60psig) when operating a single 1 ½” fire hose with nozzle. Record discharge pressure. Ref (a) Observe pump shaft packing drip rate with pump unit discharging water. Packing drip rate should be 5-60 drops per minute (60 drops per minute maximum). Record drip rate. Ref (a) Inspect exhaust hose for leaks.

The 2 basic categories of hose layouts are "simple" and "complicated". A simple hose layout can include: single lines, equal length multiple lines, equal wyed lines, and equal length siamesed lines. A single line layout is the most common hose lay. When rate of flow is increased in a hose, additional pressure is needed to overcome friction.

Electronic closed loop measurement and control of the concentrate injection rate relative to water flow provides precise concentrate to water ratios at up to sixteen (16) independent solution capable discharges. This precision flow is unaffected by discharge hose length, hose size, elevation, nozzle type or incoming water pressure.
