Webii) coefficient of viscosity η of the liquid. Therefore F ∝ η x r y v z ⇒ F = k η x r y v z, where k is a dimensionless constant. Using dimensions, the above equation can be written as [MLT – 2] = k [ML − 1 T – 1] x ×[L] y × [LT − 1] z. On solving, we get x=1, y=1, and z=1 Therefore, F=k η rv. Experimentally, Stoke found that ... WebRepresentative methods include melt mass-flow rate (MFR), melt volume-flow rate (MVR), a method using a measuring instrument such as a capillary rheometer, and bar flow evaluation using an actual injection molding machine. In general, the melt viscosity properties tend to depend on the molecular weight of the PPS polymer.
