P9.2 Consider the block diagram for liquid-level control system shown as below. If a proportional controller is used, and Km=K₁=K₂= K₂=1 P Q₁ [ft³/min] E H' P' P₁ Kp Hsp [ft] Km H [mA] [mA] Ge(s) KIP K₂ Q₂ [ft³/min] TS + 1 [mA] [psi] Hm H' Km [mA] [ft] When the controller is set to manual mode which means no control action is applied, what will be the level response h'(t) to a unit step change in P'(mA) of magnitude M.
