Water used for irrigation contains solid particles, which significantly affect macroscopic parameters, mechanical properties, flow, and water-treatment processes. This paper presents a solution to the challenge of achieving a permanent flow of an ideal biphasic medium in the open channels of a constant cross section by using an interpenetrating model of a biphasic medium. We present analytical expressions for phase speed and concentration of a two-component medium for the first time and derive relationships between speed and density of components. https://biomedpharmajournal.org/vol7no1/solution-for-permanent-flow-of-an-ideal-biphasic-medium-in-open-channels-of-a-constant-cross-section/ Biphasic medium Open channels constant cross section
