Using Poiseuille's law, the flow rate Q = (π * r^4 * ΔP) / (8 * η * L). Assuming L = 1 m, Q = (π * (0.05)^4 * 1000) / (8 * 0.1 * 1) = 0.01 m³/s.

Shear stress = viscosity × (velocity/radius) = 0.1 × (1/0.05) = 2 Pa.

Using the formula for shear stress, τ = (4 * η * Q) / (π * r^3), we find τ = 0.4 Pa.

A viscosity of 0.5 Pa·s indicates that the fluid is relatively thick and flows less easily compared to fluids with lower viscosity.

The viscosity of a liquid generally decreases with an increase in temperature.

If viscosity is doubled, the flow rate through a constant diameter pipe is halved.

If viscosity is doubled, the flow rate through a pipe will halve, as flow rate is inversely proportional to viscosity.

A high viscosity indicates that the fluid flows slowly.

According to Poiseuille's law, if viscosity is doubled, the flow rate is halved, assuming all other factors remain constant.

According to Poiseuille's law, if viscosity is doubled, the flow rate will be halved, assuming other factors remain constant.

Higher viscosity results in a lower height of rise in a capillary tube due to greater resistance to flow.

Increasing the temperature generally decreases the viscosity of a fluid, making it flow more easily.

While temperature, pressure, and fluid composition affect viscosity, fluid density does not directly affect viscosity.

The time taken for a fluid to flow through a capillary tube is directly related to its viscosity.

Viscosity generally increases when a fluid is cooled.

Fluids generally have lower viscosity at higher temperatures.

A fluid typically has the lowest viscosity at high temperatures.

Heating a liquid generally decreases its viscosity, allowing it to flow more freely.

The effects of viscosity are most prominently observed when oil pours from a bottle, as it flows slowly due to its higher viscosity.

Adding salt to water generally increases its viscosity.

For gases, viscosity increases with an increase in temperature due to increased molecular activity and collisions.

As temperature increases, the viscosity of a liquid generally decreases because the increased thermal energy allows the molecules to move more freely.

The viscosity of gases increases with an increase in temperature due to increased molecular motion.

Adding a solute to a solvent typically increases the viscosity of the solution due to the interactions between solute and solvent molecules.

Adding salt to water generally increases its viscosity.

Increasing the molecular weight of a polymer generally leads to an increase in viscosity due to longer chain lengths and entanglements.

The viscosity of gases increases with an increase in pressure.

For most liquids, increasing pressure tends to increase viscosity, although the effect is generally small.

For most liquids, viscosity decreases with an increase in temperature due to increased molecular motion.

Viscosity arises primarily from molecular interactions within the fluid, which resist flow.
