![]() In theoretical work, particularly in determining molecular masses of high polymers viscosity measurements have found very wide applications. Cosmetics: Viscosity should be considered when designing the feel and flow of cosmetic products.Concrete: Viscosity determines the self-leveling and pumping behavior of a mix.In physics, viscosity is often expressed using Isaac Newtons equation for fluids. ![]() Similar to friction between moving solids, viscosity will determine the energy required to make a fluid flow. Viscosity results from the interaction, or friction, between molecules in a fluid. Petroleum: Viscosity measurements project the effectiveness of lubricating oil and determine design elements of pipelines. Viscosity refers to the thickness of fluid.Food: Viscosity measurements are used in the food industry to maximize production efficiency and cost effectiveness.The following are examples of how viscosity measurements are used: Viscosity is a most important parameter when any flow measurements of fluids, such as liquids, semi-solids, gases and even solids are made. In the manufacture of paint, rubber, glue and synthetic polymers extensive use of viscosity measurements is made in control operation. Examples of proteoglycans are versican (a large chondroitin sulfate proteoglycan), perlecan, neurocan. Proteoglycans are a type of glycoproteins present in the body, especially in connective tissues, bone and cartilage, and cell surfaces. The diverse propulsive mechanisms of animals involve a contractile structuremuscle in most casesto. To locomote, all animals require both propulsive and control mechanisms. Viscosity of lubricating oils play an important role in their use in machines. A proteoglycan is a macromolecule that has a core protein with one or more glycosaminoglycan chains. Locomotion, in ethology, any of a variety of movements among animals that results in progression from one place to another. Viscosity is an important property in both theoretical and practical work. Coefficient of Viscosity: The force of friction required to maintain velocity difference of 1cm. This arises due to internal friction between layers of fluids as they slip past one another while liquid flows. Units of SI: Coefficient of viscosity Nm-2s(or)Pa-s.(or) Poiseuill e Units of C.G.S: Coefficient of viscosity poise. Viscosity: Viscosity is a measure of resistance to flow of liquids. Viscosity is the measure of a substance’s resistance to motion under an applied force. Viscosity: The property of a fluid which opposes the relative motion between the layers is called viscosity.
