$1.$ Figure P$1$ shows a constant head permeability test, which was performed

on a layered soil. The two soils are marked soil A and soil B$.$ at the

interface between the two soils, the pressure head was measured and

found to be hp $=1\mathrm{.}3$ ft $($datum is at lower water surface$).$

a$.$ What are the total heads at the top and bottom of soil A$?$ Plot the

pressure, elevation and total heads in the space provided.

b$.$ If the velocity of the flow through soil B is $2\mathrm{.}1$ ft$/$hr$,$ what is its

permeability?

c$.$ What is the seepage velocity in Soils A and B$.$

d$.$ What is the permeability of Soil A$.$
