Abstract
In order to estimate the behaviour of particle shape on determination of particle size by sedimentation method, effective diameters of some typical shaped specimens such as sphere, cylinder and plate were compared with equivalent and projective diameters. And the deviations between effective and projective diameters of some metal, powder (sphere, granular and plate) 'were studied by comparing with the results of model specimens. For the spherical and granular specimens, the deviations of effective diameter from equivalent or projective diameter were none or negligible, but the results of long cylinder and thin plate specimens vary greatly by the elongation of cylinder or the flakiness of plate.
These results, which could be adapted to metal powder, were showed graphically in this paper.
