consider a natural gas pipeline. The pipeline is made of steel of thickness 2.00 cm. The steel is coated on the inside with a 0.100 mm layer of Ni. The concentration of natural gas inside the pipeline is 0.100 kg/m3. The concentration outside is 0 kg/m3. The diffusion coefficient of natural gas in Ni is 2.01 x 10-21 m2/s and the diffusion coefficient of natural gas in steel is 7.00 x 10-17 m2/s. Calculate the flux of natural gas through the pipe assuming steady-state and linear geometry.

a. 1.89 x 10-15 kg/(m2.s)


b. 5.27 x 10-16 kg/(m2.s)


c. 2.00 x 10-18 kg/(m2.s)


d. 9.91 x 10-15 kg/(m2.s)

When the transportation of natural gas in a pipeline is not feasible for economic reasons, it is first liquefied using nonconventional refrigeration techniques and then transported in super-insulated tanks. In a natural gas liquefaction plant, the liquefied natural gas (LNG) enters a cryogenic turbine at 3 MPa and -160 °C at a rate of 20 kg/s and leaves at 0.3 MPa. If 115 kW power is produced by the turbine, determine the efficiency of the turbine. Take the density of...

Compressed natural gas is fed into a small underground pipeline having an inside diameter of 5.9 in. The gas enters at an initial temperature of 120oC and constant pressure of 132.3 psig. The metered volumetric flow rate at standard pressure of 14.7 psia and standard temperature of 25oC is 195.4 ft3/min. The ground temperature is constant at 15oC and serves as an “infinite sink” for heat transfer. a) Show that the mass flow rate is 0.0604 kg/sec, volumetric flow rate...

Kinder Morgan, an oil and gas pipeline company, is contemplating the expansion of its TransMountain Pipeline, which runs from Alberta to the British Columbia coast. The project is estimated to cost $7.4 billion and is expected to have a useful life of 15 years, with a salvage value of $0.5 billion. The new equipment will be added to an existing CCA Class with a rate of 5%. The pipeline expansion will increase capacity from the current level of 300,000 barrels...
