Question

If the rectangular tank full of water in Fig. P3.37 has its
right-hand wall lowered by an amount δ , as shown, water
will fl ow out as it would over a weir or dam. 
we deduced that the outfl ow Q would be given by
Q = C b g1/2δ3/2
where b is the tank width into the paper, g is the acceleration
of gravity, and C is a dimensionless constant. Assume
that the water surface is horizontal, not slightly curved as in
the fi gure. Let the initial excess water level be δ o . Derive a
formula for the time required to reduce the excess water
level to ( a ) δ o /10 and ( b ) zero.
