c) Clean filters
d) Correct fan speed
True or False
6. ___ A manometer can be used to measure static pressure in an air duct.
7. ___ TAB procedures should only be performed after system startup and commissioning.
8. ___ Air density corrections are necessary when measuring airflow at high altitudes.
9. ___ Hydronic balancing involves adjusting water flow in piping systems.
10. ___ Accurate TAB reporting is not essential as long as the system is balanced.
Short Answer
11. List two common TAB instruments used for air balancing.
12. Briefly describe the purpose of a proportional balancing method.
13. Name one key item that should be included in a TAB report.
14. Why is it important to correct air leakage in ductwork during TAB?
15. What is the difference between balancing a constant volume system and a variable air
volume (VAV) system?
Answer Key
Multiple Choice:
1. b
2. c
3. b
4. a
5. b
True or False:
6. True
7. False
8. True
9. True
10. False
Short Answer (Sample Responses):
11. Anemometer, flow hood
12. Proportional balancing ensures all outlets are adjusted relative to each other to achieve
design flows.
13. System airflow readings, equipment settings, or any deviations from design.
14. Air leakage leads to inaccurate airflow readings and energy loss.
15. Constant volume systems deliver the same airflow at all times; VAV systems adjust airflow
based on demand.
