The hydraulic resistance to a flow propagating in polyethylene 
pipelines with a velocity characteristic of flows propagating in gas-supply 
systems has been experimentally investigated. The experimental data 
have been processes statistically with the use of the maximum-likehood 
method and regression analysis. The hydraulic-resistance coefficient 
has been approximated using the Colebrook-White, Prandtl, and 
other models. Corrections to the hydraulic formulas used for calculating 
polyethylene pipelines in the process of their designing and service 
are proposed.
