Consider the liquid-level system shown below. At steady-state, the inflow rate and outflow rate are both , the flow rate between the tanks is zero, and the heads of tank 1 and tank 2 are both H. At 1-0. the inflow rate is changed from to +q. where q is small. The resulting changes in the heads ( and ) and flow rates (q; and q2) are assumed to be small as well. The capacitances of tanks 1 and 2 are C and C, respectively. The resistance of the valve between the tanks is R and that of the outflow valve is R. Tank 1 Q+q - F Tank 2 91 R + 9 (25%) 1. Derive the transfer function for the system when q is the input and he is the output. (5%) 2. What is the steady-state response of h2 due to a unit-step input?
