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 2.8 m from the impervious layer. The total depth of the second layer is 4m. The depth of water table from drain level is 2m, the recharge is 2(cm/day), and drain wetted parameter 1.5m. Find drain spacing using simplified Hooghoudt -Ernst Equation.
