###### Question details

Consider the liquid-level system shown in Figure 2. Q_bar is the
steady-state flow rate, H_bar is the steady-state liquid levels of
the fluid tank. The capacitance of the tank is C, and the
resistance of the outflow pipe is R. Assume that the variations of
the variables from the steady-state values are small, obtain the
unit-step response of the outflow rate q_{o} , i.e., the
inflow rate i q_{i} is a unit-step function.
