Extracted text: Water is flowing at a steady rate through a homogenous and saturated horizontal soil strip of 10 m length. The strip is being subjected to a constant water head (H) of 5 m at the beginning and 1 m at the end. If the governing equations of flow in the soil strip is d²H = 0 (where, x is the .2 dx? distance along the soil strip), the value of H (in m) at the middle of the strip is
