Two Types of Diagrams May bTwo types of diagrams may be referred to as the flow curve, depending on the application. One application of fluid mechanics, where the flow curve shows the relationship between fluid dynamic viscosity and shear rate. Flow curves can also be applied to pumps, in which case they illustrate the relationship between volume flow pump and the pump head.
Fluid mechanics, dynamic viscosity - also called absolute viscosity - measures fluid flow resistance. In other words, the dynamic viscosity shows that the force needed to move the liquid content. Shear is the experience of pressure fluid, because the forces that are parallel to the flow direction - mainly power tube or channel wall. Shear rate is directly proportional to fluid velocity, as soon as he passes, shear it experiences.This is called a thixotropic fluid, its viscosity increases the shear also decreased. They form the liquid material is stopped.

Many development projects focused on new or improved materials needed for making the flow behavior in the proper performance of the product. Examples include, greases, lubricants, engines, and thickening agents in food. Companies that produce these liquids and semi-solid, extensive tests the behavior of traffic flow of the initial determination of the yield curve profiling and recovery after use. The detailed methods that can be quantified and related material parameters of the viscosity requirement has caused a number of expensive research rheometers with the extensive capabilities. The disadvantage, however, not only price, but also the time needed to properly train the operators.
In addition to Ostwald viscometer, there are several other types of viscometers used. This includes decreases in viscometers, viscometers of the piston, vibrational viscometers, viscometers, and rotating bubble viscometers. Instead of measuring fluid movement, when those other types of measuring the movement of an object through a liquid, for example, fall into the piston or the rising air bubbles. Use and accuracy of various types of viscometers may vary.
Non-Newtonian fluid is defined by Sir Isaac Newton's Law Fluid mechanics and viscosity, the larger the shear rate decreases. This is called a thixotropic fluid, its viscosity increases the shear also decreased. They form the liquid material is stopped. It is impossible to directly measure the absolute non-Newtonian fluid viscosity. Apparent viscosity to be determined by the shear rate and initial temperature measurement.e Referred to as the Flow Curve
