Fluid mechanics has a wide range of applications in chemical engineering, mechanical, biological systems, and astrophysics. Explore the definition of viscosity, the equations used to measure it, and the practical uses of both. Fluid Mechanics is a branch of Physics that studies the behavior of fluid (liquids, gases, blood, and plasmas) at rest and in motion. It is defined as kinematic viscosity = viscosity coefficient (η)/density (ρ) and expressed or calculate in the Stoke unit for the honor of the scientist Stoke. Viscosity is a characteristic of thickness that describes a fluids resistance to flow. Viscosity is the measure of a substances resistance to motion under an applied force. fluid mechanics, science concerned with the response of fluids to forces exerted upon them. Kinematic viscosity in physics sometimes is used in engineering studies to compare the following property of the different liquids. The reciprocal of viscosity is called fluidity which measures the flowing tendency of the liquid to study physics and chemistry. The former liquids are called high viscous liquid while the latter liquids are called high viscous liquids. The viscosity of a fluid describes how sticky its constituent molecules are when one part of the fluid moves, it drags neighbouring parts by an amount. For example, glycerol, ester, oil flow slowly while water, ether, alcohol flow rapidly on the solid surface due to viscosity.
Viscosity is the resistance to flow exhibited by fluids (liquid or gas) like glycerol, ester, oils, water, alcohol, ether and due to the property, the flow of some liquids is slower than the other. is the fluid viscositya constant of proportionality, and is the velocity gradient perpendicular to the direction of shear. Fluid Viscosity, sometimes referred to as dynamic viscosity or absolute viscosity, is the fluids resistance to flow, which is caused by a shearing stress.
