Natural gas will be transferred from a gas well located in Sengkang to the city of Pare-Pare, South Sulawesi. This well production flowrate is 50 MMSCFD. The pipe length required for this is 70km long. Sengkang is 300m higher than Pare-Pare. Natural gas has a molecular weight of 17. The gas temperature in the pipe is assumed to be fixed at 30C. The gas inlet pressure of this pipe is 60kgf/cm2 gauge. Determine the gas outlet pressure at various pipe diameters of 5,10 , and 15 inches. Graph the relationship between the pipe outlet pressure and the pipe diameter. The allowable pipe roughness /D is 0.002
