What happen if there is no viscosity?

If there were no viscosity, then the outflowing air would be exactly the same as the inflowing air, except for the direction. Instead of separating when breathing out, the flow would spread out. As a result, we would breathe back in a lot of the air we breathed out.

Why is it important to know a fluids viscosity?

Viscosity of a liquid is an important parameter as it can be used as an indicator of quality by the consumer, in some instances a thicker liquid being thought of as superior quality when compared to a thinner product. Viscosity is also a characteristic of the texture of food.

How does viscosity affect fluids?

Viscosity is a measure of a fluid’s resistance to flow. A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion.

How does viscosity affect volume?

The more viscous a fluid is the more the volume it occupies.

What happens to viscosity of a liquid with increase in temperature?

The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature. Thus, upon heating, liquids flow more easily, whereas gases flow more sluggishly.

What is viscosity explain the cause of viscosity?

Viscosity is a measure of the resistance of a fluid towards being deformed when under shear stress. Hence, it is also known as shear viscosity. It is caused by the attractive forces between molecules in close contact, and the friction between molecular chains.

What is the importance of viscosity in pharmacy?

Viscosity is a key indicator of quality in a wide range of biotech applications, from pharmaceuticals and mechanical devices to medical laboratories and research centers. Viscosity measurement is important when it comes to determining a wide range of data points—such as at what point can a fluid flow through a syringe?

What is the importance of viscosity physics?

Similar to friction between moving solids, viscosity will determine the energy required to make a fluid flow. In physics, viscosity is often expressed using Isaac Newton’s equation for fluids, which is similar to Newton’s second law of motion.

What is the cause of viscosity in a fluid How does the flow of fluid depend on viscosity?

Internal friction is the cause of viscosity of fluid. The flow of fluid decreases when viscosity increases, because viscosity is a frictional force and greater the friction, lesser is the flow of liquid.

What is viscosity in fluids?

Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow.

How does density of liquid affect its viscosity?

In general, for any fluids, when the temperature is increased, its density decreases, thus the fluid becomes less viscous.
