Question 1
A pitot-tube traverse gives an average total pressure of 1.05 in. w.g. and an average static pressure of 0.69 in. w.g. What is the average velocity pressure?
Correct Answer:
0.36 in. w.g.
Explanation:
Velocity pressure equals total pressure minus static pressure: 1.05 - 0.69 = 0.36 in. w.g.
Question 2
At standard air density, a measured velocity pressure is 0.25 in. w.g. Using V = 4005 × √VP, what is the air velocity?
Correct Answer:
About 2,003 fpm
Explanation:
V = 4005 × √0.25 = 4005 × 0.5 = 2,002.5 fpm, or about 2,003 fpm.
Question 3
A rectangular duct is 24 in. by 18 in. and the average measured velocity is 4,500 fpm. What is the airflow?
Correct Answer:
13,500 cfm
Explanation:
The duct area is (24/12) × (18/12) = 3.0 ft². Airflow = area × velocity = 3.0 × 4,500 = 13,500 cfm.
Question 4
A fan delivers 10,000 cfm at 900 rpm. If fan speed is increased to 1,080 rpm and the system is otherwise unchanged, what airflow is predicted by the first fan law?
Correct Answer:
12,000 cfm
Explanation:
Airflow varies directly with fan speed. 10,000 × (1,080/900) = 12,000 cfm.
Question 5
A fan develops 2.0 in. w.g. static pressure at 1,000 rpm. If speed rises by 20% with no other change, what static pressure is predicted by the fan laws?
Correct Answer:
2.88 in. w.g.
Explanation:
Fan pressure varies with the square of speed. 2.0 × 1.20² = 2.88 in. w.g.

ASHI Flashcards and Exam Questions

Question: What is the recommended compression rate for high-quality CPR in adults, children, and infants? Answer and Explanation: The recommended rate is 100 to 120 compressions per minute. This specific pace ensures adequate blood circulation to the brain and vital organs during cardiac arrest.Review Flashcards →

Question: When using an AED on an adult, what is the most critical step before the device delivers a shock? Answer and Explanation: You must ensure that everyone is "clear" and no one is touching the patient. Touching the victim can result in the shock being transferred to the rescuer or disrupting the AED's rhythm analysis.Start the Free Practice Test →

Question: How deep should chest compressions be for an average adult victim? Answer and Explanation: Compressions for an adult should be at least 2 inches (5 cm) deep, but no more than 2.4 inches (6 cm). This depth is necessary to manually pump the heart and circulate blood effectively.Read the Study Guide →
