Question: 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

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 Î´h in the tank.

Pump curve, 1500 rpm valve line 40 30 m (kg/s) 20 Slope 00 10 Ap (N/m2)
