A steady state, a tank with a curved surface area of 1m2 experiences a nominal flow rate of 0.06 m3/hr. The tank's outlet flow rate is proportional to the liquid level height, as F = 0.25h. At time t = 0, the inlet flow rate abruptly increases from 0.16 m3/hr to 0.06 m3/hr and remains there. What is the maximum height at infinite time?
