3. Consider two adjacent tensiometers inserted into unsaturated sandy-loam soil to determine whether water flow is toward or away from the surface. Tensiometer A is placed at a depth of 20 cm; tensiometer 8 at 60 cm. The following readings are obtained at different times. Which way is the water flowing at each time (assuming that no maximum or minimum of tension exists between the two levels)?
