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.
Formula for DensityDensity = Mass / Volume
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/cm2 or 0.890cP at about 25°C.
The water viscosity is 0.0091 pose at 25°C or 1 centipoise at 20°C.
