A simple sink object with an inlet flow rate Qi of 20 m3/h and a level h stable at 10 m. Now, if the inlet flow rate is suddenly increased to 30 m3/h and the response curve of the level h is shown in the diagram, try to find the characteristic parameters and mathematical model of the sink object. (expressed as differential equations and transfer functions respectively, and try the final value theorem for its final steady state value) 4 () 30 20 1 (min) ) (a) ${u 13 10 1 (min)
