Figure 3-1.—Saybolt viscometer. used to express the fluid’s viscosity, in Saybolt universal seconds or Saybolt furol seconds. The glass capillary viscometers, shown in figure 3-2, are examples of the second type of viscometer used. These viscometers are used to measure kinematic viscosity. The viscometer is available in either Redwood orifice no. 1 or orifice no. 2, ensuring testability for liquids with flow of 20-2000 seconds or 2000+ seconds, respectively. Each model is available with 1, 2, or 3 positions, and comes equipped with brass oil cup with closing-ball ended rod, cup cover, and leveling screws to ensure accurate results. The Saybolt and Stokes viscometers shear the liquid in different ways. Explain how they differ? The Saybolt’s viscometer method, the shear force begins once the liquid rolls down the tube, while in the Stokes viscometers method, shear force is applied when an object, in this case a ball, runs through the liquid which therefore causes ... Experiment # 7 Objective To report the effect of temperature on the viscosity of the given sample by Saybolt viscometer. Apparatus. Saybolt viscometer Stop watch Thermometer Conical flask Beaker. Theory Viscosity is a fundamental characteristic property of all liquids. When a liquid flows, it has an internal resistance to flow. 12mm in length , This viscometer is used to determine the kinematic viscosity of the oil. From the kinematic viscosity the dynamic viscosity is determined . Theory and Definition : Viscosity is the property of fluid . It is defined as “The internal resistance offered by the fluid to the movement of one layer of fluid over an adjacent layer ‘ . The viscosimeter began as a scientific instrument for laboratory use in the 1830s. In time, due to increased industrial production, demand for quality control, and use of mineral-based oils, it gained real-world importance. The favored form for petroleum products measured the time it took for a certain volume of fluid to empty out of a container. The standard American design was developed by ... measurements from the traditional saybolt viscometer. In a previous study, a Dynamic Shear Rheometer (DSR) was used to evaluate the rheological prop erties of several types of emulsified asphalts .
