Fundamental Method for Measuring Viscosity
Fundamental Method for Measuring ViscosityA fundamental method for measuring viscosity involves a viscometer made from concentric cylinders (see Fig. 1.9). The fluid for which the viscosity is to be measured is placed between the two cylinders. The torque generated on the inner fixed cylinder by the outer rotating cylinder is determined by using a torque-measuring shaft. The force required to cause the cylinder to spin and the velocity at which it spins are also measured. Then the viscosity may be calculated in the following way:
