%X An experimental study of gas conveying of Geldart-D powder in dilute phase through a vertical pipe upwards for 18 m with internal diameter 0.05 m upwards for 18 m was conducted. The pressure drop, choking velocity, minimum fluidized velocity for fluidized bed tank and mass flow rate were measured. The values of fs obtained from the experimental pressure drop in the vertical pipe were the same as those predicted by the correlation presented by Klinzing and Mathur, Yang and Caric. The process of calculating fs also showed that the actual solids velocity, calculated from Eq.2 in the paper, in the conveying pipe was the true value. The experimental results showed that the ratio of pressure gradient along 135( upward bend, 135( downward bend and inclined pipe to the vertical pipe were 1.6, 2.0 and 4.0 respectively.
