DIPLEG SIZING AND CYCLONE PRESSURE BALANCE

Dipleg Diameter. In the foregoing examples, the minimum 4 I.D. (see Fig. 19) was sufficiently large to pass the collected solids. The basic relationship for sizing diplegs takes the dimensionless form  

If the fluid stream is a gas, the last term in the above equation is essentially unity. Unless the cyclone itself is rotating or, for example, located on another planet, g can be taken as 32.2. If the bulk solids angle of internal friction is unknown, then taking an average value of 62 degrees, the equation reduces to
