A falling-head permeability test gives the following information:
- Water flows horizontally through the soil sample.
- The soil sample length in the direction of flow is 150 mm.
- The cross-sectional area of the soil sample is 1,140 mm2.
- The cross-sectional area of the standpipe is 200 mm2.
- At the beginning of the test the height of water in the supply standpipe is 1 m above the permeameter.
- After 1 hour, the height of water in the supply standpipe is 0.95 m above the permeameter.

(a) Sketch the arrangement of the set up for this type of measurement.
(b) Calculate the hydraulic conductivity.
(c) Which is the probable tested soil?
