WebSMD is typically defined in terms of the surface diameter, ds: ds=Apπ{\displaystyle d_{s}={\sqrt {\frac {A_{p}}{\pi }}}} and volume diameter, dv: dv=(6Vpπ)1/3,{\displaystyle d_{v}=\left({\frac {6V_{p}}{\pi }}\right)^{1/3},} where Apand Vpare the surface area and volume of the particle, respectively. WebFor non-spherical particles, it is seen that Vv =VT = is un- This is now in quite simpli6ed form. It is seen, 6rstly, that changed, and the surface area of a single particle is Ap =!d2p , there is no reason for either the sphericity or porosity to now de6ned in terms of the non-spherical particle diameter. be listed separately in Eq.
