The Viscosity of Air Calculator is a valuable tool used to determine the viscosity of air at a specific temperature. Understanding air viscosity is essential in various industries, including aerospace, automotive engineering, and climate science. This calculator utilizes a mathematical formula to compute the viscosity based on input parameters such as temperature and Sutherland’s constant.
Formula of Viscosity of Air Calculator
The formula used in the Viscosity of Air Calculator is as follows:
μ = μ_ref * (T / T_ref)^(3/2) * (T_ref + S) / (T + S)
Where:
- μ: Viscosity of air at the given temperature (in units of viscosity, typically Poise or Pascal-seconds).
- μ_ref: Viscosity of air at the reference temperature (usually 273.15 K or 0°C), typically around 1.81 x 10^-5 Pa*s.
- T: Temperature at which the viscosity is being calculated (in Kelvin).
- T_ref: Reference temperature, usually 273.15 K or 0°C.
- S: Sutherland’s constant for air, typically around 110.4 K.
Table of General Terms
Here’s a table of general terms related to air viscosity that people commonly search for:
| Term | Description |
|---|---|

Example of Viscosity of Air Calculator
Let’s say we want to calculate the viscosity of air at a temperature of 300 Kelvin (K) with a Sutherland’s constant of 110.4 K. Using the formula provided, we can plug in the values and compute the viscosity:
μ = (1.81 x 10^-5) * (300 / 273.15)^(3/2) * (273.15 + 110.4) / (300 + 110.4) μ ≈ 1.81 x 10^-5 Pa*s
So, the viscosity of air at 300 K is approximately 1.81 x 10^-5 Pascal-seconds.
Most Common FAQs
Air viscosity refers to the resistance of air to flow. It is a measure of how “thick” or “sticky” air is, affecting its behavior in various scenarios such as fluid dynamics, aerodynamics, and heat transfer.
Understanding air viscosity is crucial in industries such as aviation, automotive engineering, and meteorology. It influences factors like drag on vehicles, heat transfer in HVAC systems, and the behavior of fluids in pipelines. By calculating air viscosity, engineers and scientists can optimize designs and make informed decisions.
