The formula to calculate the density of water is:
\[ D = 1000 \left( 1 - \left( \frac{(T + 288.94)}{5089 (T + 68.1296)} \right) (T - 3.986)^2 \right) \]
Where:
The density of water is determined by the temperature of the water only, since water is incompressible and not affected by pressure.
It's important to keep the units of measure of temperature consistent throughout the use of the formula.
Let's assume the following value:
Using the formula:
\[ D = 1000 \left( 1 - \left( \frac{(300 + 288.94)}{5089 (300 + 68.1296)} \right) (300 - 3.986)^2 \right) \approx -26,546.24 \, \text{kg/m}^3 \]
The density of water is approximately -26,546.24 kg/m³.
