Research analyzes velocity distribution and resistance in turbulent flow in channels, indicating accuracy with measurements.

The study aims to calculate a unified velocity distribution for incompressible turbulent flow in a two-dimensional channel.
Calculated velocity distribution using linear expression for shearing stress.
Assumed polynomial expression for mixing length.
Introduced laminar sublayer to align with laws of wall and velocity defect law.
Achieved velocity distribution coincides with established flow laws.
Derived resistance formula correlates well with existing experimental measurements.

Matsumiya et al. (1967) studied this question.
