A 20-cm long soil sample is acquired with a cylindrical tub having a 5-cm diameter. On removal from the tube, a sample weighs 525 g. After it is oven dried at 105° C for a period of 48 hours, the weight has stabilized at 503.2 g. The sample is assumed to be stabilized at this point and soil water has been removed. Compute the bulk density, porosity, water content, and water saturation.

Determine the volume of water flowing through the sample shown in the figure per hour. There are 3 different soil layers and each is 200mm in length and diameter is 150mm. A constant head of 470mm is maintained across the soil sample. The porosity for Soil I is 0.5 and the value of k is 5*10^-3 cm/s. The porosity for Soil II is 0.55 and the value of k is 4.2*10^-2 cm/s. The porosity for Soil III is 0.35 and the value of k is 3.69*10^-4 cm/s. The hydraulic conductivities are measured in the direction of the flow.
