Q3
Figure Q3 shows a flow net for flow through a weir, the base of which
is 2m below the ground surface, in a permeable soil layer. Given that
the coefficient of permeability =k = 5×10-³ cm/sec, determine the
following:
- 14 m
7 m
8 m
2 m
10 m
kx = k, = k
Impermeable laye
Figure Q3
a) Total head (m) at point a, b, c, d, e, and f.
b) Uplift pressure (or water pressure, kPa) at point a, b, c, d, e, and f.
c) The total rate of seepage per unit length through the permeable
layer.
d) The approximate average hydraulic gradient at point f.
