A large soil specimen with a trapezoidal longitudinal$-$section is tested using a constant head permeameter $($the figure is drawn to scale$).$

a$)$ indicate the initial and final equipotential lines and the first and last flow lines.

b$)$ determine the total head at point $A.$

c$)$ if the flow is measured to be $0\mathrm{.}005\frac{m^3}{h}r$ and the specimen dimension in the direction of the paper is $0\mathrm{.}5m,$ what is the hydraulic conductivity of the soil?Given the two square footings, determine the vertical induced stress on point $A$
