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
Pressure loses due to friction inside the hose are 5 psi for every 100-feet of hose length The hose has to be 50,000-feet (9.47-miles) long to have 0 psi at exit end. Practical hose length limit: 200-ft 200-ft is long but still practical, about half the length of a soccer
