Consider the liquid storage system in Fig. E8.13. Suppose that q_{1} must be kept constant, and, consequently, h_{2} is to be controlled by adjusting q_{2}. Suppose that the q_{2} control valve is fail-close. Should the level controller for h_{2} be reverse acting or direct-acting? Justify your answer.
