Viscosity of Water Calculator

Formula

The formula to calculate the viscosity of water (μ) is:

\[ \mu = A \cdot \left(1 - \frac{T}{B}\right)^C \]

Where:

Viscosity of Water: The measure of water's resistance to gradual deformation by shear or tensile stress. It is often referred to as the 'thickness' or 'stickiness' of the water.
Energy Difference (ΔE): The difference in energy between two states, measured in joules.
Boltzmann Constant (kB): A physical constant relating the average kinetic energy of particles in a gas with the temperature of the gas, approximately \( 1.380649 \times 10^{-23} \) J/K.
Temperature (T): The measure of the thermal energy of a system, measured in Kelvin.

Let's say the temperature is 25°C. Using the formula:

\[ \mu = 1.0020 \times 10^{-3} \cdot \left(1 - \frac{25}{20}\right)^{1.5} \]

We get:

\[ \mu \approx 0.00089 \text{ Pa.s} \]

So, the viscosity of water at 25°C is approximately 0.00089 Pa.s.
