【简答题】A typical liquid storage process is shown in Fig1, where qi and q are volumetric flow rates. Derive the transfer function model from qi to level h considering two cases. (8pts) 1)The flow may be assumed to be linearly related to the driving force, the liquid level, in analogy to Ohm’s law for electrical circuits (E=IR). That is, h=qRv, where Rv is the resistance of the exit pipe. (4 pts) 2)A more realistic expression for flow rate q is linear to the square root of the liquid level h, that is,(4 pts)Fig1. A liquid-level storage process.
