![A steady, constant-head flow of water has been established through a square prism of
saturated soil, as shown (next page), with all dimensions given in cm.
(A) Complete (by hand) a reasonably precise sketch of a flow net through the prism of
soil with exactly 5 flow lines and 9 equipotential lines.
(B) How many equipotential drops (also known as potential or piezometric drops) will
the flow of water experience from point B to point D?
(C) How much exactly is the head loss (total head loss) for each equipotential drop?
(D) If the reference datum coincides with the bottom of the soil prism, determine the
elevation head, pressure head, total (piezometric) head, and pore-water pressure
(g/cm?) at all points A through E. (Note: density of water = 1.0 g/cm'.)
