The paper describes the structure of the filtration curve built in a wide range of variation of filtration rates. A detailed description of the mechanism of occurrence and development of the inertial component of the filtration flow structure is given. Equations are presented that can be used to approximate the filtration curve. A modified equation is proposed that provides a smooth transition from laminar to turbulent filtration without discontinuities of the velocity and pressure fields, which can be used when calculating both one-dimensional and spatial filtration flow.
