CETA Calculations Exam Questions and Answers

Explain how to determine particles measuring in cubic feet per minute and reporting them in cubic meter per minute. - Take your total counts of 24 per cubic feet per minute and multiply by 35.2 = 844.8. Round up to 845 cubic meters per minute Explain how to calculate air changes per hour from PEC - Length x width x fpm = CFM. Total CFM divided by room volume x 60 = ACPH per that particle PEC. Explain how to determine minimum CFM required from ceiling HEPA filters in HD room. - Take minimu...

CETA Calculations Graded A+ 1. Calculate Air Changes Per Hour (ACPH) To calculate air changes per hour, you first need to determine the room's volume and the total airflow from HEPA filters. - Room Volume: - ( text{Room Volume (cubic feet)} = text{Length} times text{Width} times text{Height} ) - Total CFM from HEPA filters: Measure the airflow in cubic feet per minute (CFM) from all HEPA filters in the room. - ACPH Calculation: - ( text{ACPH} = left( frac{...
