Method of experimental investigation of the friction facility pneumatic wires

Aim. Development of a method for experimental study of the coefficient of friction for pneumotransport systems of gaseous media using the method of similarity and dimensionality theory, which allows expanding the number of factors and they intervals by grouping them into dimensionless similarity criteria. Method. The planned experiment was chosen for experimental studies of the coefficient of air friction. The main factors were pressure, diameter of the pipeline, air flow.
