The angle of the widening section must not be greater than 15º.

Industrial exhaust duct design.

10 1 duct fittings and transitions. Exhaust stack and air intake design strategies stack design strategies the dilution a stack exhaust can pr ovide is limited by the disper sion capability of the atmosphere. 10 2 volume control dampers. Air ducts friction loss diagram a major loss diagram for air ducts imperial units ranging 10 100 000 cfm.

Friction in a system means the fan needs to work harder and this results in higher operating costs. Duct systems include straight lengths or sections of duct transitions elbows and bends enlargements or contractions hoods discharge stacks and hangers or supports. Duct fittings and terminal units. Volume velocity x area.

Installing engineering controls is the preferred method of. Air ducts sizing air flow and required duct area. Our products are used to serve a variety of needs including industrial ventilation dust extraction and pneumatic conveying. The larger perimeter also means more air will come into contact wit the material and this adds friction to the system.

Design of ducts with side junctions side duct junctions. The rectangular duct therefore requires more metal for its construction this adds more weight and costs to the design. Ivi can assist in the design of a new system or the redesign of an existing system. 10 4 diffusers grilles registers.

A side duct should join the main one at a tapered progressive widening and at an angle of 30º or less recommended or up to 45º or if there is insufficient space.
