Let A$,$ B$,$ and C refer to the points of measurement of piezometers A$,$ B$,$ and C$.$

Calculate:

a$)$ The hydraulic heads at A$,$ B$,$ and C $($m$).$

b$)$ The pressure heads at A$,$ B$,$ and C $($m$).$

c$)$ The elevation heads at A$,$ B$,$ and C $($m$).$

d$)$ The water pressures at A$,$ B$,$ and C $($N$/$m$2)($the water density is $1000$

kg$/$m$3$ and the gravity constant is $9\mathrm{.}81$ m$/$s$2)$

e$)$ What are the magnitudes of hydraulic gradients between A and B$,$

between B and C$,$ and between A and C$?$

f$)$ What are the flow directions between A and B$,$ between B and C$,$ and

between A and C$?$
