Consider the liquid-level system treated in Example 7.4.10 and shown in Figure 1 A.M. The pump curve and the line for the steady-state flow through both valves are shown in Figure. It is known that the bottom area of the tank is 2 m2 and the outlet resistance is R2 = 400 l/(m/s).
(a) Compute the pump resistance R1 and the steady-state height,
(b) Derive a linearized dynamic model of the height deviation δh in the tank.
