it is soil mechanics cores. determine the question. A soil sample 10 cm in diameter is placed in a tube 1 m long. A constant supply of water is allowed to flow in to one end of the soil at A and the outflow at B is collected by a beaker. The average amount of water collected is 1 cm* 1cm*1cm for every 10 seconds. The tube is inclined as. determine the (a) hydraulic gradient, (b) flow rate, (c) average velocity, (d) seepage velocity, if e= 0.6, and (e) coefficient of permeabilityge velocity, (d) seepage velocity, if e= 0.6, and (e) coefficient of permeability.
