Syska Hennessy Group, the international engineering firm, has launched an app called the Ductulator, which helps architects, owners, contractors, and mechanical engineers easily determine and specify ...

Careful planning in designing ductwork for emission control structures goes a long way toward reducing overall plant construction costs. Increasing restrictions on power plant emissions are causing ...

In 1948, research by R.G. Huebscher established flow resistance for different shapes of ductwork at equal velocities, which allowed the creation of the duct-sizing calculator or “Ductulator” for ...

For the past 50 years, engineers have been “designing” duct systems. Quite often, they were not actually designing the systems, but were sizing duct the duct according to some rule of thumb. The rules ...
