Consider the tank level control system shown in the figure, where the cross-sectional area of the tank is A. Assume perfect flow controllers (FC). The level controller (LC) is proportional-integral (PI). For an integral time, Ο, the level controller gain, KI, is tuned for critical damping. The value of KI is ________ (rounded off to the nearest integer).
Correct : 4.24
