Unformatted text preview: products. Note that some of the water will condense out, since this temperature is below the dew point. 4. The lean ﬂammability limit of methane – which describes the minimum concentration of methane in air that can be ignited – corresponds to a equivalence ratio of Φ min = 0 . 5. Say a natural gas pipe begins leaking into a basement room, of volume V = 200 m 3 , at a rate of ˙ V g = 2 L/min. The natural gas (which can be taken to be methane) becomes completely mixed with the air in the room. Assuming the room stays at 1 atm total pressure, how long will it take for the air in the room to become explosive? 1...
