Ventilation Rates<br />
Ventilation rates of work areas for health physics <strong>and</strong> industrial<br />
hygiene requirements is typically 6 to 7 volume turnovers per<br />
hour.<br />
Calculate the ventilation rate in CFM to ventilate a room at 7<br />
volume turnovers per hour given room dimensions of 30 feet by<br />
30 feet by 10 feet. Volume of the room is 30 x 30 x 10 = 9,000<br />
cubic feet. Seven volume turnovers per hour would be 7 times<br />
9,000 cubic feet or 63,000 cubic feet per hour (1,050 CFM)<br />
room ventilation rate.<br />
