Abstract
Formulae are derived to calculate the mass median (DO) and mass mean (DM) diameters of droplets in sprays. These formulae are based on an inverse exponential relationship which is empirically observed to occur in liquid sprays. The median diameter divides the total mass of liquid in half while the mean diameter represents a more commonly used statistical average for identifying random samples. The formulae are used to describe the characteristics of a typical set of experimental drop data and are compared to conventional formulae for calculating these parameters.
