  • Capillary Rheometry: Analysis of Low-Viscosity Fluids, and Viscous Liquids and Melts at High Shear Rates
    Rheology is defined as the study of the. flow and deformation of fluids. Based. on the need to quickly and accurately. set and control processing conditions, optimize. product performance, and/or ensure. product acceptance, accurate rheological. measurements have become essential
  • Viscosity & Rheology Classroom
    The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. It is a measure of the resistance of flow due to internal friction when one layer of fluid is caused to move in relationship to another layer.
  • Viscosity Measurment Application Notes
    Most laboratory viscometers employ the well-known principle of rotational viscometers to measure viscosity by sensing the torque required to rotate a spindle at a constant speed while it is immersed in the sample fluid. This is because the torque, generally measured using the reaction torque
  • Universal Viscosity Curve Theory
    Like any transducer, a turbine flow meter is sensitive to physical parameters other than the one which is of interest. While designed to measure flow, a turbine meter responds to the viscosity of a fluid as well as its velocity. Following is a brief discussion of the viscosity sensitivity
  • A New Way to Handle Changing Fluid Viscosity and the "Full-to-empty" Effect
    This paper explains how the Ultimus( TM) V High Precision Dispenser and Optimeter (TM) maintain consistent shot size in time-pressure dispensing processes as the fluid viscosity and volume of fluid remaining in the syringe change.
  • Viscosity of Ionic Liquids
    Ionic liquids are employed as powerful, environmentally neutral. solvents and as electrically conducting fluids. Due to exact viscosity. determination with the Lovis 2000 M/ME microviscometer essential. information on their chemical structure, composition and purity can. be gained.
  • Ask the Expert: Measuring the Viscosity of an Oil
    Viscosity is the measurement of an oil's resistance to flow. Typically, we can expect viscosity to decrease with a temperature increase, and increase with a temperature decrease. Viscosity and temperature are considered to be inversely proportional. In oil analysis, viscosity is commonly measured
  • Why Should You Measure Viscosity?
    Viscosity is the measure of a substance's resistance to motion under an applied force. Are you working with Newtonian or Non-Newtonian Fluids? From adhesives to paint and food to petroleum - viscosity is important.
