RESEARCH UNSTEADY A PRESSURE HEAD PIPE FLOW BASED ON MATHEMATICAL MODELS

The article deals with mathematical modeling of non-stationary processes non-periodic pressure of the fluid in cylindrical tubes. Based on the Navier-Stokes equations for compressible fluid withdrawn simplified equation for the case of long pipes. It is shown that modeling of single processes, these equations contain only one dimensionless parameter. Identifies conditions which may further simplify these equations to a form that does not contain a dimensionless parameter.
