2. Duct (flow) - Wikipedia

   en.wikipedia.org/wiki/Duct_(flow)

   Aluminium ductwork is lightweight and quick to install. Also, custom or special shapes of ducts can be easily fabricated in the shop or on site. The ductwork construction starts with the tracing of the duct outline onto the aluminium preinsulated panel. The parts are the

3. Process duct work - Wikipedia

   Round ductwork allowable compressive stress is = 662 /(d/t) +339 * Fy (tubular steel structures, chapter 2). Other reference use similar equations. Ductwork typical cement plant pressure drops are: 60% to 80% of high temperature process duct work pressure drop occurs in the process equipment, baghouses, mills and cyclones. Since motor 1 (one ...

4. Duct (industrial exhaust) - Wikipedia

   en.wikipedia.org/wiki/Duct_(industrial_exhaust)

   Industrial exhaust ducts are pipe systems that connect hoods to industrial chimneys through other components of exhaust systems like fans, collectors, etc. Ducts are low-pressure pneumatic conveyors to convey dust, particles, shavings, fumes, or chemical hazardous components from air in the vicinity to a shop floor or any other specific locations like tanks, sanding machines, or laboratory hoods.

5. Heating, ventilation, and air conditioning - Wikipedia

   Warm air systems distribute the heated air through ductwork systems of supply and return air through metal or fiberglass ducts. Many systems use the same ducts to distribute air cooled by an evaporator coil for air conditioning. The air supply is normally filtered through air filters [dubious – discuss] to remove dust and pollen particles. [15]

   A diffuser is placed over ductwork, and it separates air with vanes going in differing directions. It evenly distributes air flow in the desired directions. dry bulb temperature Dry bulb temperature is the temperature of air measured by a thermometer which is freely exposed to the air while it is shielded from radiation and moisture.
