Extracted text: Vinyl chloride, with a permissible exposure limit (PEL) of 1 ppm, evaporates into the air at a rate of 7.5 g/min. Assuming that a safety factor of at least 5 is used to ensure proper dilution, determine the flow rate of air that will be required to achieve the PEL, utilizing dilution 2-3 ventilation.
