• New analysis and a definition of the new mean particle size have been discovered by rediscussing theory of the buoyancy weighing-bar method, which is a type of sedimentation methods. This paper proposes a new mean particle size based on the settling velocity in liquid. The velocity mean size of all particles [equation], which is the new mean particle size defined in this paper by the buoyancy weighing-bar method, is given as follow.[equation]ΔGi is the buoyancy difference mass of particles xi. Homogenous particles and a ternary mixture of spherical glass beads are used as the samples. Although the buoyancy weighing-bar method is also time-consuming, the maximum particle size and the mean particle size can be derived within a short time after initiating measurement.
