p. Flow nets. Consider seepage beneath a dam through a homogeneous, isotropic,permeable, fully saturated foundation rock (Fig. 1). A larger version of Fig. 1 is provided at the back of

this exam paper. Draw a quantitatively accurate flow net, with n = 5 flow tubes, on it. Attach the page to your exam script prior to submission. i) How much will the water rise if a piezometer is placed at the middle of the base of the dam (marked R in Fig. 2)? (ii) Determine the seepage loss of the dam if K = 10* m/s. Fig. 2 presents the dimensions of the base of the dam. Calculate the uplift forc under the base of the dam. For simplicity, take fluid density to be p =1000kg/m and the gravitational acceleration to be g = 10m/s".
