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 B per unit length of dam The permeability of the silty sand is 0 05 ft min The drawing is to scale Use the scaled drawing for your flow net sketching and pressure calculations evaluations Upstream water level is at El 200 ft Downstream water level is at El 162 ft Dam is 105 ft long and bottom is at el 146 ft Ground surfaces on both upstream and downstream sides are at El 150 ft T EL 200 FT EL 150 FT TH ht 52 5k 105 FEET LONG FLO F rock THEO by do 20 El 162 FT
