The coefficient of permeability below a dam is 4m/day. The water on the upstream side is 20m higher than on the downstream side. To estimate the seepage below the dam, a flownet was graphically drawn such that the number of potential drops Nd=10 and number of flow channels Nf=4. The base of the dam is founded 1m below the ground. Between the heel and the toe of the dam, a distance of 30m, there are 8 potential drops. Evaluate the seepage flow per meter width of the dam in liters per minute. Determine the uplift pressure at the heel of the dam in kPa
