Purpose. Determination of the actual values of the hydraulic resistance of pressure fire hoses based on experimental and theoretical studies for use in the calculation of pump-hose systems.
Methods. To achieve this goal, an experimental method was used, based on determining the pressure loss (pressure) in the hose line by establishing the pressure difference at the beginning and end of the hose line, followed by calculating the resistivity of a fire hose running meter, and then multiplying the resistance of a fire hose running meter sleeves to its length.
Findings. A comparative analysis of the hydraulic resistance values of pressure fire hoses with a diameter of 77, 66, 51 mm was performed. It has been found that currently used values may differ significantly depending on the source of information. A technique for performing measurements in the course of research on pressure losses in pump-hose systems has been developed. Experimental studies have been carried out and the main indicators of the hydraulic resistance of pressure fire hoses with a diameter of 77, 66, 51 mm have been determined.
Application field of research. Fire tactics, calculation of pumping and hose systems.
