## What is Density?

Density is a fundamental characteristic of matter easily understood by water, described by the compactness of particles within a given spatial extent. Mathematically, density is ascertained by dividing the mass of the entity by its corresponding volume.

Density = Mass / Volume

Formula for Density

Mass is typically measured in kilograms (kg) or grams (gm), while volume is gauged in cubic meters (m³) or cubic centimeters (cm³).

The unit of measurement for * density *relies on the chosen metrics for mass and volume. For instance, if mass is expressed in grams and volume in cubic centimeters, density is denoted in grams per cubic centimeter (g/cm³). Similarly, if mass is specified in kilograms and volume in cubic meters, density assumes the form of kilograms per cubic meter (kg/m³).

## What is Dynamic Viscosity?

Dynamic viscosity describes how “thick” or resistant a fluid is to flow when a force is applied to it. It determines the rate at which adjacent layers of the fluid move past each other.

The* dynamic viscosity* of water is 8.90 x 10

^{-4}Pa.s or 8.90 x 10

^{-3}dyn.s/cm

^{2}or 0.890cP at about 25°C.

The ** water viscosity** is 0.0091 pose at 25°C or 1 centipoise at 20°C.
