Stp 12 4 A Flow Of Methane Gas V S 31 000 Nm3 H Is To Be Delivered From A Well To A Distribution Facility 1 (96.85 KiB) Viewed 13 times

stp = = = = > 12.4 A flow of methane gas (V's = 31 000 Nm3/h) is to be delivered from a well to a distribution facility using a compressor located at the well-head. The gas must arrive at the distribution facility with p exit = 200 kPa, abs through a long pipeline with inside diameter D = 0.3 m , length L = 2.25 km , and absolute roughness ε = 0.3 mm. The gas leaves the compressor at T = 293 K and the flow is isothermal throughout the long pipe run. The dynamic viscosity of the methane may be assumed constant at x = 1.1 10-5 kg/m · ?.s. What pressure must be developed at the compressor discharge to accomplish this objective? Show your work. Answer. 2429 kPa (absolute)
