WebFeb 1, 1995 · The elongational viscosity of two different cooked cornmeal dough was determined as a function of moisture content (55-70% wet basis) and differences in cornmeal structure using the lubricated squeezing flow technique. When the flow regime was not governed by the viscoelastic effect, cooked cornmeal dough could be described … WebOct 21, 2024 · 1 Introduction. Capillary viscometry is still the most widely used experimental technique to determine viscosity of molten polymers. Despite theoretical simplicity, its correct application becomes rather cumbersome and may lead to measurement errors in some relevant cases, such as natural fiber filled polymers.
WebApr 4, 2024 · Viscometry is the experimental determination of the viscosity of liquids and gases with so-called viscometers. Definition of viscosity (Newton’s law of fluid friction) Viscosity describes the internal resistance to flow of a fluid (internal friction). It is defined by the shear stress τ required to shift two plates moving relative to each other.
