A gas compressor station discharge 18MMSCF per day into a pipeline (OD=6.625 inches) at 900psia and 120°F to deliver to a plant 3.5 miles away. The gas has a molecular weight of 19.5 and specific heat of 0.65 Btu/lb°F. The pipeline is coated with conventional Yellow-Jacket coating, and the soil type is silty gravel. The ground temperature for this location is 25°F. You can ignore any effects of pressure losses in the pipeline.
a) Determine the temperature of the gas at the pipeline outlet, assuming full flow, and with no additional heating along the pipeline route.
HOW CAN I CALCULATE THE OUTLET TEMPERATURE, I AM A BIT CONFUSED AS THERE ARE SO MANY INFORMATION.
