- Title
Laminar Flow of a Viscous Liquid in the Entrance Region of a Circular Pipe.
- Authors
Kazakov, L. I.
- Abstract
An approximate theory of stationary axisymmetric laminar flow of a viscous incompressible fluid in the entrance region of a circular pipe is presented. It gives correct (within ±2%) calculated values of different physical characteristics of the established flow, which coincide with the known calculated and experimental data. Instead of the traditional Bernoulli equation for the entire length of the entrance region, the work at hand uses the equation of the axial pressure gradient averaged over the pipe section to determine the pressure value.
