Guideline for Flow and Pressure Testing of Hydrants

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 pressure. For example, if the measured static pressure is 2.2 bar, then the fire flow should be measured at a rating pressure of 1.1 bar. 3.1.3 Whilst …

Hoses - Water Flow and Pressure Losses

Example - Water Flow through a Hose and Pressure Loss. 2 gpm (7.6 liter/min) flows through a 1/2" garden hose with length 82 feet (25 m). From the diagram above the pressure loss per 100 feet can be estimated to 5 psi. The pressure drop in the hose can be calculated as. (5 psi/100 ft) ( (80 ft) / (100 ft)) = 4 psi (0.28 bar)
