Equations to calculate the properties of air

• Density of air (ρ) vs. Temperature (K)
  ρ = 360.77819 * T^-1.00336
  (R²=0.99997)
  Unit : Temp(K) and Density (Kg/m³)

• Kinematic viscosity (ν) of air vs. Temperature
  ν = -1.1555e-14 * T³ + 9.5728e-11 * T² + 3.7604e-08 * T – 3.4484e-06
  (R²=0.99997)
  Unit : Temp(K) and Kinematic viscosity (m²/s)

• Dynamic viscosity (μ) of air vs. Temperature
  μ = ν * ρ
  Unit : Temp(K) and Dynamic viscosity (Kg / m s)

• Temperature
  K = 273. + °C

• Molecular weight of air = 28.75
