Below is a small sample of our exam prep questions:

(1)  A contractor must build a 15,000 square foot educational auditorium. What would be the minimum outdoor ventilation in CFM?

      • Correct Answer: IMC – Table 403.3.1.1 Auditoriums = 0.06 CFM/Sq-Ft. Therefore, 15,000 Sq-Ft x 0.06 CFM/Sq-Ft = 900 CFM

      • Correct Answer: ACCA Ductulator (duct slide rule) align 0.095 on galvanized metal duct /w 1000 cfm = 14″ round duct

(3)  Solve for minimum size of iron pipe that can be used in the following situation; Piping system 165-foot, Cubic feet / hr of gas 900 at 1 psi, Specific gravity 0.6, Pressure drop 1/2 inch water column.
