A perching layer with a K value of 0.01 m/day supports a perched ground- water body 1 m high. The perching layer is 0.5 m thick and the downward- flow rate through the perching layer is 0.038 m/day. What is the pressure head at the bottom of the perching layer? Assume that K of the material above the perching layer is so large compared to K of the perching layer itself that the perching water table can be used to indicate the pressure head at the top of the perching layer.
