Abstract
In order to study the laminar motion of viscous fluid in open channels of parabolic cross-section, the Newtonian viscosityof fluid is considered, according to which the friction between the liquid layers is proportional to the velocity gradient. In parabolic channels, the study of the motion of viscous fluid in a gravitational field, is reduced to the integration of the Poisson equation, according to the established boundary conditions. Regularities in the distribution of velocities and tangential stresses have been obtained, which make it possible to perform quantitative analysis of running hydrodynamic processes.
