The terminal velocity of single particle was studied long ago by both experimental and theoretical methods. But the research on terminal velocity of particle group has not been done yet. By experimental research, the authors have found that the terminal velocity u_t of particle group decreases linearly in proportion to the concentration μ_* of particle group and the pressuredrop increases in proportion to the weight of particle group for μ_*=0〜130. Next, the pressure drop in pneumatic conveying of wheat was calculated, applying the above relation between u_t and μ_*. Comparing this with the usual calculation (u_t=const.), it has been found that both calculated pressure drops are approximate to the experimental value at the same degree. This shows that the usual calculation (u_t=const.) is sufficient to be used for calculating the pressure drop.
