Program permits fast solution to pipeline loop requirements
A program developed for the HP-41CV hand-held calculator can provide pipeline engineers with a quick and easy means for determining loop requirements on existing gas-transmission pipelines. Adding pipe in parallel to an existing pipeline, referred to as looping, is necessary to insure that with a given flow rate, the gas will arrive at a certain point on the pipeline with a pressure equal to or greater than the minimum required pressure. The automatic loop program calculates loop by first determining the total number of segments which require looping within the section of pipeline being evaluated. A section of pipe is usually the pipeline between compressor stations and is divided into segments by either receipt or delivery points along the pipeline. The number of segments which require looping is found by adding loop to individual segments until the final pressure (i.e., the pressure at the point of interest downstream on the pipeline) is equal to or greater than the specified design pressure.
