Inertance

Inertance is the ratio of an acceleration-like quantity to a force-like quantity when the arguments of the real (or imaginary) parts of quantities increase linearly with time.

Acoustics

Describes the inertial properties of a gas in a duct.
where
L = inertance [kgm-4]
ρ0 = density of the gas [kgm-3]
Δx = incremental distance [m]
A = cross-sectional area [m2]
