of the more commonly used parameters are the mass median (DO) and mass mean (DM) diameters of the droplets. The mass median diameter re-presents the droplet diameter at which half the mass of liquid is above and half the mass of liquid is below. However, because the mass is re-lated to the cube of the diameter, it is found that the mass median

Percentiles can be shown as percent larger and indicates the volume percent larger than the size shown. The "50 percent point" is the "median diameter" or D50 and represents one type of average particle size.

For particle size distributions the median is called the D50 (or x50 when following certain ISO guidelines). The D50 is the size in microns that splits the distribution with half above and half below this diameter. The Dv50 (or Dv0.5) is the median for a volume distribution, Dn50 is used for number distributions, and Ds50 is used for surface ...

Count Median Diameter (CMD) When statistically describing lognormal distributions, the geometric mean diameter (D g) of normal distributions is replaced by the count median diameter (CMD). In lognormal distributions, the log of the particle size distribution is symmetrical, so the mean and the median of the lognormal distribution are equal.
