3. A liquid storage system is shown below. The normal operating conditions are q:=10ft/min,qz=5 ft/ min, h=4ft. The tank is 6ft in diameter, and the density of each stream is 60lb/fts. Suppose that a pulse change in q2 occurs (a) What is the transfer function relating H to Q ? ? (b) Derive an expression for h(t) for this input change. (c) What is the new steady-state value of liquid level h? (d) Repeat (b) and (c) for a change in q : from 10 to 20 (at t=0 ) to 15ft// min at t=12
