Determining the consumption coefficient for modeling the coating system for inner surface of rotating pipe

The article is devoted to determining the flow coefficient in mathematical modeling of the operation of a new device for coating the inner surface of pipes for rooms with a limited height. A new method for coating the inner surface of a pipe in a confined space, in which the pipe being worked is in an inclined position and rotates around its axis during the process, is described. The thickness of the coating depends on the speed of movement of the material. The more precisely the speed stabilizes, the more uniform the protective coating is. The authors considered methods for determining the flow coefficient; the methods for its determination were described. The numerical values of the flow coefficient for a specific liquid-pipe pair have been obtained.
