Pressure is defined as force per unit area, and its SI unit is Pascal (Pa).

The SI unit of viscosity is Pascal-second (Pa·s), which is equivalent to Newton-second per square meter.

Fluidity refers to the ability of a fluid to flow easily.

Hydrostatic pressure refers to the pressure exerted by a fluid at rest due to the weight of the fluid above it.

Viscosity is the measure of a fluid's resistance to flow, indicating how thick or thin the fluid is.

Viscosity is the term used to describe the resistance of a fluid to flow.

The upward force exerted by a fluid on a submerged object is known as buoyancy.

The upward force experienced by an object submerged in a fluid is known as buoyancy.

The unit of surface tension is Newton per meter (N/m).

Surface tension is defined as force per unit length, hence its unit is Newton per meter (N/m).

Young's modulus is defined as stress divided by strain and is measured in Pascals (Pa).

The viscosity of water at 20°C is approximately 0.001 Pa·s.

Newtonian fluids have a constant viscosity that does not change with the shear rate.

A Newtonian fluid has a constant viscosity that does not change with the shear rate.

Adding a surfactant to water decreases the surface tension by disrupting the cohesive forces between water molecules.

Poiseuille's law is used to calculate the viscosity of a fluid in a capillary tube.

Poiseuille's law is used to calculate the viscosity of a fluid in a pipe.

Poiseuille's law describes the flow of a viscous fluid through a capillary tube and relates viscosity to flow rate.

Charles's Law states that the volume of a gas is directly proportional to its absolute temperature at constant pressure.

The elastic limit is the maximum stress that a material can withstand without undergoing permanent deformation.

The shear modulus is defined as the ratio of shear stress to shear strain in a material.

Poisson's ratio (ν) is defined as the ratio of lateral strain to longitudinal strain.

Gases have no definite shape or volume and will expand to fill the entire volume of their container.

Viscosity is a measure of a fluid's resistance to flow.

Dynamic viscosity can be calculated using Poiseuille's law.

In a Newtonian fluid, shear stress (τ) is directly proportional to the shear rate (du/dy) with the proportionality constant being the dynamic viscosity (μ).

Density does not directly affect surface tension; it is influenced by temperature, impurities, and the nature of the liquid.

The buoyant force depends on the density of the fluid, the volume of the object submerged, and the acceleration due to gravity, but not on the depth of the object.

The buoyant force depends on the volume of fluid displaced, the density of the fluid, and the acceleration due to gravity, but not on the shape of the object.

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