Question
Q) Two liquid storage systems are shown in the figure below .Each tank is 4
feet in diameter.For system I,the valve acts as a linear resistsnce with the
flow-head relation q=8.33h ,where q is in gal/min and h is in feet. For
system Il,variations in liquid level h do not exit flow rate q.Suppose that
each system is initially at steady state with =6 ft and =50 gal/min and that
at time t=0 the inlet flow rate suddenly changes from 50 to 70 gal/min.For
each system,determine the following information:
a)The transfer function H(s)/Qi(s).
b)The transient response H(t).
c)The new steady state levels.
d)lf each tank is 8 ft tall,which tank overflows first?when?
Note:(1 gal/min=0.1337ft/min)
