A constant head permeability test has a soil sample length in the direction of flow of350 mm, a sample cross sectional area normal to the flow direction of 125 cm2, and ahead loss through the sample of 420 mm. The soil sample is a medium dense sand with avoid ratio of 0.61. During a 3 minute test period, 580 cm3 of water flowed through thesample. (a) Sketch the Constant Head Permeameter and label the sketch with theappropriate dimensions given above. (b) Determine the Hydraulic conductivity, k, incm/sec, and the seepage velocity (not just apparent velocity).
