Question
Transcribed Image Text:5.1. Derive the transfer function H(s)/Q(s) for the liquid-level system of Fig. P5-1 when
(a) The tank level operates about the steady-state value of h, = 1 ft
(b) The tank level operates about the steady-state
value of h, = 3 ft
9, ft/min
The pump removes water at a constant rate of
10 cfm (cubic feet per minute); this rate is inde-
pendent of head. The cross-sectional area of the
tank is 1.0 ft“, and the resistance R is 0.5 ft/cfm.
h(t)
5.2. A liquid-level system, such as the one shown in
Fig. 5-1, has a cross-sectional area of 3.0 ft². The
valve characteristics are
2 ft
