    Abstract To theoretically and experimentally study the kinetics of the spreading of a drop of Newtonian liquid over a solid surface in order to increase the flow capacity of water supply systems for various purposes (water supply, fire suppression, etc.) and the fire-extinguishing properties of water. Methods. Mathematical modeling. Experimental studies. Results. A kinetic equation describing the spreading of a drop of Newtonian liquid over a solid surface was obtained. A compar ison was made with experimental data. Scope of the research. The obtained results are important for further research in the field of extinguishing solid building materials and the capacity of water supply systems.
    Keywords: contact angle, equilibrium contact angle, surface tension coefficient, dynamic viscosity, kinematic viscosity, dynamic meniscus, pipeline, fire extinguishing properties, water supply system
