Fluid Inertia

Model the effect of fluid inertia in a pipe

 Description The Fluid Inertia component models the effect of fluid inertia in a pipe, that is, the pressure differential is proportional to the rate of change of the flow rate.
 Equations $p={p}_{A}-{p}_{B}=\frac{L\mathrm{\rho }}{A}\frac{\mathrm{d}q}{\mathrm{d}t}$ $q={q}_{A}=-{q}_{B}$
