Measuring Airflow in Local Exhaust Ventilation Systems. Module 23. Vocational Education Training in Environmental Sciences.
Consumer Dynamics Inc., Rockville, MD.
This module, one of 25 on vocational education training for careers in environmental health occupations, contains self-instructional materials on measuring airflow in local exhaust ventilation systems. Following guidelines for students and instructors and an introduction that explains what the student will learn are three lessons: (1) naming each part of the swinging vane anemometer and describing its function; (2) assembling the anemomenter and checking its operation; and (3) making velocity measurements in hoods and ducts within the measurement accuracy of the anemometer used. Each lesson contains objectives, recommended methods and locations for practice, performance criteria, equipment and supplies to perform a task, detailed step-by-step instructions for learning a task, and performance exercises. Two performance tests cover checking the operation of the swinging vane anemometer while assembling it, and making air velocity measurements in hoods and ducts. (CT)
