A numerical method has been developed for calculating the losses and property variations in very long insulated steam pipelines. This method is based on the fundamental equations of compressible fluid flow and heat transfer, and utilizes computer software for evaluation of steam properties. Examples illustrate the effects of different inlet conditions, mass flows, and insulation thicknesses. Choking occurs under some conditions.
