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
	$p = p_{A} - p_{B} = \frac{L ρ}{A} \frac{d q}{d t}$ $q = q_{A} = - q_{B}$

Variables
