Flow Dynamics in Connected Liquid Tanks

This model investigates the flow dynamics between three liquid tanks connected by two pipes (the first pipe connecting Tank 1 and 2, and the second pipe connecting Tank 2 and 3).  The liquid level in each tank oscillates due to the flow inertia in each pipe. Flow inertia is damped by pipe friction, and eventually the liquid height in each tank reaches equilibrium.

A Maple worksheet that models the system from a first-principle momentum balance is also attached (see Project > Attachments > Documents > OscillatingTanks.mw).  In the Maple worksheet, differential equations that describe a momentum balance and the dynamic change in liquid height in each tank are solved numerically.
