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)
