Problem 1: Carbon Monoxide Diffusion in a Building Hall Suppose a 3m long hall connects an underground parking garage polluted with CO at 34mgm3. The hall is 1m wide and 2m tall. At the end of the hall is an office where ventilation maintains the CO level at 10mgm3. If the diffusion coefficient is 0.5m2min1 what is the CO max flux toward the office
