## About Viscosity of Air Calculator (Formula)

A Viscosity of Air Calculator is a tool or formula used to estimate the viscosity of air at a given temperature. Viscosity refers to a fluid’s resistance to flow, and it plays a crucial role in various engineering and scientific applications. Understanding air viscosity is important in fields such as fluid dynamics, heat transfer, and aerodynamics.

**Formula for Viscosity of Air Calculation:**

The viscosity of air changes with temperature, and its calculation involves using mathematical models or empirical correlations. One commonly used empirical correlation for the dynamic viscosity of air (μ) as a function of temperature (T) in degrees Celsius is:

**μ = A * 10^(B / (T + C))**

Where A, B, and C are constants specific to the units being used for viscosity and temperature. The formula’s constants can vary depending on the source and the units used (SI or Imperial), so it’s important to ensure consistency in units.
