Air flow Drag force Gravity Droplets are swept by the air motion and fall due to gravity. Their fall is resisted by a drag force Droplets evaporated to become droplet nuclei Turbulence mixing dilutes the droplet concentration Ballistic trajectory of large droplets from sneezing mode Droplets land on a surface and dries to become desiccated. Bed making activities can eject dry particles into the air 1-2 metres Dilution of contaminated air from breathing mode [Source : ASHRAE.org] Theoretical aerobiology of transmission of droplets and small airborne particles produced by an infected patient
