Consider the following storage tank shown in Fig. E.3. The volumetric flow rateare varied with time. The valve used on the outlet flow is linear with resistanceR₁ = 0.3. The cross-sectional area of the tank is 3 m². The height of the liquid inthe tank at steady-state condition 4 m. Answer the following:a) Obtain a transfer function relating liquid level with inlet flow rateH'(S)Q₁(s)b) For a step-change in the inlet flow from 3m³/s to 4m³/s, find the final valueof the height of the liquid in the tank.
