Viscosity Comparison between Water and Mercury

Viscosity is the measure of a fluid's resistance to flow. It is a crucial parameter in the study of fluid mechanics. Water and mercury are two common fluids used in various applications. Let's compare the viscosity of water and mercury.

Viscosity Definition

Viscosity is defined as the measure of a fluid's resistance to flow. It is also defined as the internal frictional force that opposes the motion of one layer of fluid over another layer.

Viscosity Formula

The formula for viscosity is given by:

η = F/A x t/v

Where,
η is the viscosity
F is the force applied
A is the area of contact
t is the time taken
v is the velocity

Viscosity of Water

The viscosity of water is affected by temperature and pressure. At room temperature, the viscosity of water is 0.001 Pa.s (Pascal-second). It is a low viscosity fluid and is commonly used in various applications.

Viscosity of Mercury

The viscosity of mercury is also affected by temperature and pressure. At room temperature, the viscosity of mercury is 0.0015 Pa.s (Pascal-second). It is a higher viscosity fluid than water.

Comparison of Water and Mercury Viscosity

Water and mercury have different viscosities. The viscosity of water is lower than that of mercury. This means that water flows more easily than mercury. The viscosity of mercury is higher than that of water, which means that it resists motion more than water.

Conclusion

In conclusion, the viscosity of water is lower than that of mercury. This makes water flow more easily than mercury. The viscosity of a fluid is an important parameter in fluid mechanics and affects the flow of fluids in various applications.

Kinematic viscosity of water is higher as compair to mercury because mercury has high density
