Pressure Loss Calculator | Pacific Hoseflex

Keep in mind that if you transfer gaseous substance through the hose then you need to find the ratio of the density of gas over the density of water and adjust the pressure drop respectively. For example if you transfer natural gas (density = 0.050 lb/ft 3) and knowing that water density = 62.4 lb/ft 3 we can find out the pressure drop as the following: 3.7 x (0.050/62.4) = 0.0030 psi/ft or 0

Pressure Restricting Hose Valves | American Fire Supply

Pressure restricting hose valves are used to restrict the pressure of flowing water up to 175 PSI. They are angle hose valves with preset orifices which restrict the volume of water and thereby lower the pressure of the flowing water. NFPA requires restricting valves where the inlet pressure exceeds 100 PSI. Pin may be removed by firefighters to allow fully open valve. Unlike pressure
