A Soil Sample 10 cm in diameter is placed in a tube 1 m long. A constant supply of water is allowed to flow into 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 cubed for every 10 seconds. The tube is inclined as shown in the figure. Determine the (a) hydraulic gradient, (b) flow rate, (c) average velocity, (d) seepage velocity if e = 0.6, and (e) hydraulic conductivity. Strategy: In flow problems, you must define a datum position. So your first task is to define the datum position and then find the difference in total head between A and B. Use the head difference to calculate the hydraulic gradient and use the appropriate equations to solve the problem.
