HVAC Ducting Principles and Fundamentals
www.pdhonline.com3. High Velocity Duct Systems: High-velocity (HV) duct systems are characterized by air velocities in the range of 2500 to 3500 fpm. Low-velocity ductwork design is very important for energy efficiency in air distribution systems. Low-velocity design will lead to larger duct sizes, but it may be worth since, doubling of duct diameter

www.rses.orgThe velocity through the filter in this example would be 500 ft/min (V = 2000 cfm ÷ 4 ft2 = 500 ft/min). PRINCIPLES OF AIR PRESSURE As air travels through a conduit, it creates a pressure called velocity pressure (VP). There is a relationship between velocity of the air and the velocity pressure based on the density of the air. This ...
