WA) Derive the transfer function H(S)/Q(s) for the liquid-level system of the below figure when a) The tank level operates about the steady-state value of hs=1 ft. The tank level operates about the steady-state value of hs=3 ft. The pump removes water at a constant rate of 10 ft /min; this rate is independent of the head. The cross- sectional area of the tank is 5 ft, and the resistance R is 0.5 f/A?/min. 9, ft3/min (b) fo, ft3/min qo=WR ht) 9p, ft3/min 2 ft
