CALCULATOR : Gas Pipeline Average Flowing Temperature And Pressure [FREE] ±

Calculate gas pipeline average temperature and pressure.

In general, pipeline temperature decays exponentially along the length of the pipeline, and the pressure drops in proportion to the distance squared. The average temperature and pressure are approximate only.

For average temperature, the ambient temperature and the pipeline insulation is assumed to be constant along the length of the pipeline. The inlet and outlet temperature must be either both above the ambient temperature, or both below the ambient temperature, and may not be equal to the ambient temperature.

For average pressure, the pipe slope is assumed to be constant along its length.
