Q6/a: A soil of two layers has a hydraulic conductivity of 8(cm/day) for the first layer, and 2.5(m/day) for the second layer. There is a boundary level which separate the two layers and the location of the boundary is after the first layer. The drain is installed on the second layer at a distance of 3.2 m from the impervious layer. The total depth of the second layer is 5m. The depth of water table from drain level is 2.5m, the recharge is 2.7(cm/day), and drain wetted parameter 0.3m. Find drain spacing using simplified Hooghoudt - Ernst Equation. 85.13 m 90.13 m O 105.13 m

Question
Q6/a: A soil of two layers has a
hydraulic conductivity of 8(cm/day)
for the first layer, and 2.5(m/day) for
the second layer. There is a boundary
level which separate the two layers
and the location of the boundary is
after the first layer. The drain is
installed on the second layer at a
distance of 3.2 m from the
impervious layer. The total depth of
the second layer is 5m. The depth of
water table from drain level is 2.5m,
the recharge is 2.7(cm/day), and drain
wetted parameter 0.3m. Find drain
spacing using simplified Hooghoudt -
Ernst Equation.
