4 45 Points Determine the rate of seepage in cubic feet min under the dam by drawing flow net to scale and also determine the total uplift force in psf acting at the bottom of the dam at Point C per unit length of dam The permeability of the silty sand is 0 66 ft min The drawing is to scale Use the scaled drawing next page for your flow net sketching and pressure calculations evaluations Upstream water level is at El 94 ft Downstream water level is at El 68 ft Dam is 85 ft long and bottom is at el 57 ft Ground surfaces on both upstream and downstream sides are at El 64 ft U
