A class 10(10 particles/ft^3 > 5 mu m diameter) cleanroom is designed with 9 - foot high ceilings. To maintain this level of cleanliness, 50 air exchanges per hour are required (the total volume of air in the room is replaced with new air 50 times/hour). What is the total number of particles that would hit a surface one square foot in an area perpendicular to the airflow in 1 minute? 1 hour? 24 hours?
