WebNov 1, 2015 · In this paper we follow a similar approach to analyse the dynamic powder behaviour in the FT4 Powder Rheometer for cohesive particles. 2. Materials and methods. In order to allow for accurate simulations by DEM, 1.7–2.1 mm spherical glass beads are used in this work, with the size distribution given in Fig. 1. WebA rotational viscometer measures the dynamic viscosity [ƞ] of a sample. Newton's Law defines the dynamic viscosity η as the shear stress divided by the shear rate. When we measure the viscosity on a rotational viscometer we apply to the sample a certain shear stress or a certain shear rate, respectively. $\eta = {{\tau} \over {\dot{\gamma}}}$ grand canyon annual weather
