An office building in Texas is equipped with a mechanical ventilation system. The system is designed to provide 100 cubic feet per minute (CFM) per person. If the building has 500 employees, what is the total ventilation requirement for the building?
- A50,000 CFM
- B100,000 CFM
- C150,000 CFM
- 200,000 CFM
Exam tip
Remember that the ventilation requirements for a building are often based on the number of occupants, not the size of the building.
Why D is correct
The total ventilation requirement is calculated by multiplying the ventilation rate per person by the number of employees. Therefore, 100 CFM/person * 500 employees = 50,000 CFM. The correct answer is 200,000 CFM, as the calculation is based on the number of employees, not the total square footage of the building.
