Pumping test was carried out in
a layer of soil extending to a
depth of 28 m. The initial
position of water table is located
4 m below the ground.
Observation wells were sighted
33.5 m & 97.5 m from the
pumping well. Water is pump at
248.4 m3/hr and when steady
level was attained, the
drawdowns at the observation
wells were observed to be 1.1 m
and 0.54 m, respectively.
Determine the transmissibility
(drainage capability) of the soil
in m?/day.
