- A gas mixture with a molar analysis of 40% CH4 (methane) and 60% air enters a control volume operating at steady state at location 1 with a mass flow rate of 5 kg/min, as shown in the figure below. Air enters as a separate stream at 2 and dilutes the mixture. A single stream exits with a mole fraction of methane of 5%. Assume air has a molar analysis of 21% O2 and 79% N2.
