Cyclone design equations formulas calculator air filtration quality purification pollution control. A 2d2d cyclone has barrel and cone lengths of two times the barrel diameter, whereas the 1d3d cyclone has a barrel length equal to the barrel diameter and a cone length of three times the barrel diameter. These three cyclone designs have the same inlet dimensions (hc and bc), referred to as the 2d2d inlet.
