Flow property of fluids, including powder and liquid, was examined by using the variable rotating cylinder method. A large difference and similarlity were observed in the rotating speed of samples of powder and liquid in rotation adhering completely to the inner wall of the variable rotating cylinder. Correlation was found between the viscosity of liquid and the rotating speed in some liquids. On the other hand, rotating speed seemed to express a physical value related to the flow property considered to be the deformability against stress other than the viscosity.
