Standard Cyclone Dimensions
Extensive work has been done to determine in what manner dimensions of cyclones
affect performance. In some classic work that is still used today, Shepherd and Lapple
(1939, 1940) determined "optimum" dimensions for cyclones. All dimensions were
related to the body diameter of the cyclone so that their results could be applied
generally. Subsequent investigators reported similar work, and the so-called "standard"
cyclones were born. Table I summarizes the dimensions of standard cyclones of the
three types mentioned previously. Figure 3 illustrates the various dimensions used in
