ConstantValue
\(R_g\) (air)287.058 J/(kg·K)
\(\gamma\) (air)1.4
\(c_0\) at 300 K, 1 atm343 m/s
\(\rho_0\) at 300 K, 1 atm1.2 kg/m³
\(p_0\) (atmosphere)101 325 Pa
Sample rate \(f_s\)44 100 Hz
\(\mu\) (air, 300 K)1.84 × 10⁻⁵ Pa·s
\(k_f\) (air, 300 K)0.026 W/(m·K)
\(c_p\) (air)1005 J/(kg·K)
\(c_v\) (air)718 J/(kg·K)

Note: The specific heats are computed as \(c_p = \frac{\gamma}{\gamma-1} R_g\) and \(c_v = \frac{1}{\gamma-1} R_g\).
