Consider 20 standard cubic meters hydrogen cyanide (HCN) has been rapidly released in an underground subway. For this scenario the subway is a tube 20 meters in diameter. Assume that the diffusivity is E ≈ 5x104 cm2 s-1. The density of HCN in gaseous form can be used as 0.000761 g/cm3. At 100 meters away from the release point, estimate the time required for the hydrogen cyanide concentration to rise to dangerous levels? Assume an air conditioning system is moving the air in the tube toward you at about 0.3 m/s. How does this alter the time estimate?
