The volumetric analysis of a mixture of gases is 30 percent oxygen, 40 percent nitrogen, 10 percent carbon dioxide, and 20 percent methane. This mixture flows through a 1.6-cm-diameter pipe at 8000 kPa and 15oC with a velocity of 5 m/s. Determine the volumetric and mass flow rates of this mixture
(a) Treating it as an ideal gas mixture.
(b) Using a compressibility factor based on Amagad's law of additive volumes.
(c) Using Key's pseudocritical pressure and temperature.
