Polevoda, I. Karpenchuk, M. Striganova, É. Shatilo] A model of turbulent flow of a rheological solution of a foaming agent in a cylindrical channel of an automatic fire-extinguishing system is proposed; this model allows for the viscous stresses produced in the region of hydraulic roughness of the channel. Integral equations are obtained for calculation of the flow velocity and rate of flow of the foaming agent in the indicated channel, and also of the hydraulic resistance and head loss in it. Recommendations on practical use of the proposed theoretical model have been developed.
