Coefficient of viscosity air Calculator

In flight mechanics, the coefficient of viscosity of air refers to the dynamic viscosity of air, which is a measure of its resistance to deformation or flow. Dynamic viscosity is a fundamental property of fluids that quantifies the internal friction or “stickiness” between layers of fluid as they move past each other. It is a crucial parameter in aerodynamics and fluid mechanics, as it influences the flow behavior and shear forces experienced by an aircraft in the air.

μ = 1.458 * 10^(-6) * (T^(3/2)) / (T + 110.4)

Where: μ = Dynamic viscosity of air (in Pa·s or N·s/m²) T = Temperature of air (in Kelvin)
