Consider the tank level control system shown in the figure, where the cross-section area of the tank is 𝐴. Assume perfect flow controllers (FC). The level controller (LC) is proportional-integral (PI). For an integral time, 𝜏Ι, the level controller gain, 𝐾C , is tuned for critical damping. The value of is ________ (rounded off to the nearest integer).
