2. a Gas is transported through a steel pipe of 6-inch diameter at a temperature of 68F, a pressure of 200 psia, and a velocity of 200 ft/s at the compressor outlet, which is near the pipeline inlet. Find the pressure in the pipe at a distance of 500 ft downstream by assuming (a) incompressible flow and (b) compressible isothermal flow.
