AIR FLOW RESISTANCE PER 100 m OF AN UNDERGROUND OPENING

AIR FLOW RESISTANCE PER 100 m OF AN UNDERGROUND OPENING

The basic linear resistance is often applied to the resistance systematization as the specific resistance of a 100 meter length of an underground ventilation airway. In standard environment the characteristics of such specific resistance are influenced by the room dimensions and relative roughness v...
