The response of two tanks of same size and resistance in series is __________________?
Correct answer: B. Critically damped
- A. Under damped
- B. Critically damped
- C. Over damped
- D. None of the above
Explanation
Two identical non-interacting tanks in series give a denominator proportional to (τs + 1)², which has two equal real poles. In the standard second-order form this corresponds to a damping ratio of one, or critical damping.
