Answer:
time = 224 days
Explanation:
given data
thick = 30 m
piezometers = 280 m
head between two = 1.4 m
aquifer hydraulic conductivity = 50 m
porosity = 20%
solution
we get here average pole velocity that is get by using Darcy law that is
Va = ................1
here Va is average pole velocity and k is hydraulic conductivity and is porosity
here v is = ...........2
v = 50 ×
v = 0.25 m/day
and here average linear velocity Va will be
Va =
Va =
Va = 1.25 m/day
travel time for water will be
time =
time = 224 days
