1) A soil sample from a compaction site is placed in a 15 ft long semi-circular pipe (as shown in the figure) of 2.4 ft outer diameter. The thickness of pipe is 0.1 ft. Total volume of void space per foot length in the soil mass is 0.6 ft'. A constant supply of water is maintained to flow into one end of the soil at A and the outflow at B is collected in a measuring cylinder. In average, 0.7 ft' of water was collected in 3 minutes. The tube is inclined as shown in the figure. Please determine: a) Hydraulic gradient b) Flow rate c) Average velocity d) Seepage velocity e) Hydraulic conductivity of soil in cm/s Constant level water tank 10 ft 12 ft A Porous stone 15 ft X- Flow B soil 3 2 Section X-X Measuring jar 10 ft Due date: 10/12/2017, Thursday Table 1.3 ft
