1. For a given soil sample the following data were measured. During sample collection, water table was observed at a depth of 40 cm below the soil surface. Assume that the reference is placed at the water table. Based on this information and the one in the table, fill-in the missing values of component potentials and the total hydraulic head: 7 points
