find the relation for coefficient of viscosity in terms of two given liquid?
Answers
Answer:
Viscosity is defined as the degree up to which a fluid resists the flow under an applied force; it is measured by the tangential friction force acting per unit area divided by the velocity gradient under conditions of streamline flow.
An important rheological measurement that is closely related to the resistance to flow is called viscosity.
The Viscosity of a fluid described as the resistance of liquid. For example liquids like water, alcohol, petrol and more flow freely and faster than glycerin solution, honey, and oil. This is because of its physical property and is called viscosity. In simple words, it explains the fluid’s flow resistance.
The coefficient of viscosity of fluids will be decreased as the temperature increases, while it is inverse in the case of gases. While the coefficient of viscosity of gases will increase with the increase in temperature. The increase in temperature for the fluid deliberate the bonds between molecules. These bonds are directly associated with the viscosity and finally, the coefficient is decreased.
An important question most people do not ask is, why even measure Viscosity? The main reason behind this being, that viscosity data on a material gives manufacturers a chance to predict how the material will react and behave when consumers interact with it.
The most simplistic formula for measuring viscosity is:
Viscosity=shear stressshear rate
