Is there an equation that relates viscosity of water to temperature? If not, is there a reliable table somewhere on the internet? I'm searching for the viscosity at 20°C ± 3°C.

The viscosity of water at room temperature (20 degrees Celsius) is around 0.001 Pa*s. However, this value can vary depending on the purity and pressure of the water.
The viscosity of water decreases as the temperature increases. This is because as the temperature rises, the water molecules have more kinetic energy and can move more freely, resulting in lower resistance to flow.
The relationship between temperature and viscosity of water is inverse. As the temperature increases, the viscosity decreases and vice versa. This relationship is known as the Arrhenius equation.
The unit of viscosity for water is typically measured in Pascal-seconds (Pa*s) or centipoise (cP). However, other units such as poise (P) and centistokes (cSt) may also be used depending on the measurement method.
Yes, the viscosity of water can be affected by impurities. Impurities can alter the molecular structure of water, leading to changes in its viscosity. Additionally, impurities can also increase the friction between water molecules, resulting in a higher viscosity.
