Industrial Ventilation – LEV Testing
A
The center line velocity pressure in a 15 cm (6”) diameter duct is 32 mm w.g. (314 Pa or 1.26” w.g.). What is the average air flow rate through the duct? Assume STP (21 C, 760 mm Hg).
B
The temperature of heated air from a furnace is 121°C (250°F) at an altitude of 610 m (2,000 ft). If the average velocity pressure measured (by Pitot tube method) in the outlet duct of the furnace is 27.9 mm w.g. (273 Pa or 1.10” w.g.), what is the average velocity in the duct?
