Peculiarities Connected with Determining the Dynamic Component of Full Pressure in Hydraulic Calculations of Flow in Channels in a 1D Statement

摘要

Motion of incompressible fluid in a channel is analyzed in a ID statement, and formulas for calculating the dynamic component of full pressure drop are presented that take into account variations of flow density and velocity over the channel length. It is shown that application of Bernoulli's formula for calculating this component is incorrect in certain cases.
