It is said that designing a powder unit operation device is difficult. Hence, many of the devices are being manufactured by trial and error. The lack of correlation or connection between the output of the unit operation and the physical properties and/or characteristics of powders is the anticipated reason for this trial and error process to be needed. To advance this process, many have attempted to make a connection between the particle properties and/or powder characteristics with the result of the operation. In this manuscript, some attempts to make the connection were introduced.The oldest attempt was reported by the pioneer of powder technology. This original approach gives us many suggestions on how to best proceed. Thus, outlines of the pioneer's investigation will be introduced. Following the investigation, a concept of "Powder operational characteristics" will be explained. An example of the definition and measurement of the powder operational characteristics relating to the disruption of particle aggregate by air flow is introduced. Another example of the definition of powder operational characteristics obtained through "analysing the basic powder science in a practical and applicable way" is also introduced.
