Simple shear flow-Suppose that a certain grade of a polymer/Graphene nanocomposite is subjected to a simple shear flow testing procedure. The flow is Newtonian. When the polymernanocomposite melt was sheared at a constant rate of 0.04 min-1 at 235C, the measured shear stress was 100-Pa. In order to obtain the same value of the shear stress at 250C, what rate of shearing should be used in the simple shear flow experiment? Tm of the polymer matrix is 220C, activation energy=18000 J/mol and R=1.99 cal/(mol K).
