Smoke Exhaust Duct Air Velocity at Glenn Kahl blog

Smoke Exhaust Duct Air Velocity. 5.2.1(g)(i) to (iii) and (h) which pass through one or more floors shall be masonry. Stack exhaust velocity calculations must be based on the minimum total flow rate from the system, not the maximum. An exception to these exhaust. Most cases the air in a duct is assumed to be incompressible, an assumption that overlooks the change of air density that occurs as a result of. Versions of mechanical smoke extract 1. Exhaust duct and mechanical ventilation ducts serving areas specified in cl. Courtesy of wade, spearpoint, bittern & tsai (2007) The duct velocity in air condition and ventilation systems should not exceed certain limits to avoid unnecessary noise generation and pressure drop. Powered smoke and heat exhaust ventilators (shevs systems for smoke and heat ventilation) 2. Flow velocity in air ducts should be kept within certain limits to avoid noise and unacceptable friction loss and energy consumption. The intent of the limited air velocity is to reduce the risk of fresh air mixing with the hot smoke layer and accelerating the speed the hot smoke drops down to occupant exposure levels.
