Question No. 139

Water is flowing at a steady rate through a homogeneous 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 equation of flow in the soil strip is $\frac{{d}^{2}H}{d{x}^{2}}=0$ (where x is the distance along the soil strip), the value of H (in m) at the middle of the strip is ___________
