Consider a continuous flow holding tank shown. dh dt The tank height is modeled as Aq-Ch where A is the cross-sectional area, h is the tank height, q, is the volumetric input flow rate, and C, is the valve coefficient. (a) Linearize the model equation around steady state height h. Pg Cross-sectional area=A H Pa (b) Let us define the deviation variables H=h-h, and Q=9-9. Express the model equation in terms of deviation variable and take the Laplace transform of the equation expressed in deviation variables to find the relationship between H(s) and (s). (c) When there is a step change in Q,(t) with a magnitude Q, what is the steady state value of H(t)? (Note: You don't have to calculate the h, value.)
