Abstract Experimental data for the minimum elutriation velocity u me of solids for 134 different systems have been correlated by\documentclass{article}\pagestyle{empty}\begin{document}$$ {\mathop{\rm Re}\nolimits} _{me} = \left( {2.75} \right)\left( {10^4 } \right)\left( {d_p /d_t } \right)^{1.71} \left[ {\left( {\rho _s - \rho _f } \right)} \right]^{0.47} \left( {H/H_s } \right)^{0.19} $$\end{document}The ranges of the different groups investigated were as follows:\documentclass{article}\pagestyle{empty}\begin{document}$$ 0.67 \le \left[ {\left( {\rho _s - \rho _f } \right)/\rho _f } \right] \le 3.33;\,0.00369 \le \left( {d_p /d_t } \right) \le 0.0096\,{\rm and}\,2.74 \le \left( {H/H_s } \right) \le 23.21 $$\end{document}For all of the experiments, the fluidizing liquid was water and the tube had an inside diameter of 4.92 cm. The standard deviation for the above correlation is 21.6 per cent.
