where h, and h2 are the height of the liquid in Tank 1 and 2, Aqand Azare the cross-sectional areas
of the Tank 1 and 2, R1 and R2 are orifice radiuses, p is the density of the fluid, and g is the gravity.
Liquid enters the first tank at the rate of q; and then flows to the second tank at the rate of q, then
1000
leaves the second tank at the rate of qo. If pg = 1000, A, = 250, A2 =
R = 2, R2 = 3/2
in proper units,
a) Find the homogenous solution of the system by taking the first element of the eigenvectors
as 1 if q = 0.
b) Find the non-homogeneous solution of the system using the variation of parameters method
if qi = 250.
