Two liquid storage systems are shown below. Each tank is 1.2 m in diameter. For System I, the valve acts as a linear resistance with the flow-head relation F=C, -h where F is in L/min and h is in m. For System II variations in liquid level h do not affect the exit flow rate F. h System I System II Suppose that each system is initially at steady state with h=2 m and F-190 L/min. At time t=0 the inlet flow rate suddenly changes from 190 to 265 L/min. For each system determine th following information: a. The transfer function (s)/F(s). b. The transient response h(t) (from h(t)). c. The new steady-state levels. d. If each tank is 3 m tall, which tank overflows first? When?

Transcribed Image Text:Two liquid storage systems are shown below. Each tank is 1.2 m in diameter. For System I, the valve
acts as a linear resistance with the flow-head relation F=C, -h where F is in L/min and h is in m.
For System II variations in liquid level h do not affect the exit flow rate F.

Suppose that each system is initially at steady state with h' = 2 m and F = 190 L/min. At time
t=0 the inlet flow rate suddenly changes from 190 to 265 L/min. For each system determine the
following information:
a. The transfer function (s)/F(s).
b. The transient response h(t) (from h(t)).
c. The new steady-state levels.
d. If each tank is 3 m tall, which tank overflows first? When?
