Transcribed Image Text:

The owner of a smoky bar in a warm climate relies on natural exchange between the bar and outside to keep smoke levels manageable in the bar (below 50 microgram/m³). Smokers account for a smoke PM10 source of 0.5 mg/s in the bar. If the diffusivity between bar and outside is 10 m²/s, what will be steady PM10 concentration in the bar? How would the concentration in the bar change if they enlarged it by increasing depth to 30 m without changing the opening to outside? Would smoke PM10 levels still be manageable?
