However, it is the oil’s resistance to flow and shear due to internal friction that is being measured in this example, so it is more correct to say that the gear oil has a higher absolute viscosity than the turbine oil because more force is required to stir the gear oil.įor Newtonian fluids, absolute and kinematic viscosity are related by the oil’s specific gravity. The force required to stir the gear oil will be greater than the force required to stir the turbine oil.īased on this observation, it might be tempting to say that the gear oil requires more force to stir because it has a higher viscosity than the turbine oil. Use the rod to stir the oil, and then measure the force required to stir each oil at the same rate. To measure absolute viscosity, insert a metal rod into the same two beakers.
Which one will flow faster from the beaker if it is tipped on its side? The turbine oil will flow faster because the relative flow rates are governed by the oil’s kinematic viscosity. Imagine filling a beaker with turbine oil and another with a thick gear oil. The course takes you beyond pass/fail criteria, to an understanding of how to apply viscometric data as a problem solving and product performance/processing tool.An oil’s kinematic viscosity is defined as its resistance to flow and shear due to gravity.
Focusing on test methods and techniques, it will review and discuss how Brookfield rotational viscometers and rheometers can be used to provide meaningful product analysis. "Applied course on viscosity test methods" is designed for the intermediate to advanced Brookfield Instrumentation user in R&D, Analytical, and Process Engineering functions. Participants are encouraged to bring product samples for testing where hands-on time is provided in a relaxed laboratory environment. The course is designed to benefit all operators from beginner to advanced. "Practical course on viscosity measurements" provides attendees with the tools and concepts they need to make the most precise viscosity measurements possible. Arrangements can also be made to conduct courses at customers’ facilities where content can be adapted to their specific product applications. The courses are offered at Brookfield’s headquarters in Middleboro, MA., and at major metropolitan areas across the United States. These one-day training sessions are presented in easy-to-understand terms that give attendees the working know-how to verify and improve upon the data required for meaningful R&D and successful QC testing. Brookfield (USA), manufacturers for viscosity measurement and control, offers two hands-on courses that equip users of Brookfield instruments with the knowledge to get the most out of their viscosity test methods.
