The handling of gasoline is a routine occurrence. Yet spills can happen from time to time and vaporization occurs. Under certain conditions, the gasoline vaporized exceeds the TLV of 300.0 ppm. The TLV is called the Threshold Limit Value, and is the maximum safe condition for human exposure. A spill of gasoline occurs such that a pool 2.00 m in diameter is formed in an area that has a ventilation rate of 100.0 m3/min. If the air velocity is 3.00 m/s, what is the steady state concentration (in ppm) of gasoline fumes in the enclosed area? Use a diffusivity of gasoline in air of 10-5 m2/s, assume that the temperature is 25.0°C, and assume the pressure is 1.00 atm. The vapor pressure of gasoline (MW = 94.0) at 25.0°C is 31,700 Pa.
