Permeability of soil sample problems
WebFree water or gravitational water having property to flows through soil under the action of gravity and flow of water depends upon the permeability of the soil and the head ,the most important factor related with permeability in soil is hydraulic gradient. Important point of influence in permeability in soil. 1. Soils is porous materials. 2. WebThe following data are for a falling-head permeability test:• Length of the soil sample = 140 mm• Diameter of soil sample = 70 mm• Area of the standpipe = 19.6 mm2• At time t = 0, head difference = 500 mm• At time t = 7 min, head difference = 350 mma. Determine the hydraulic conductivity of the soil (cm/sec)b.
