Calculate high temperature pipeline axial friction force and equivalent axial friction factor for multi layer pipelines.
The axial friction can be calculated for buried and unburied pipelines, and for either cohesive or non cohesive soil. The equivalent friction factor is equal to the axial friction force divided by the pipe weight.
