1.A concrete sewer pipe 1m in diameter is laid so it has a drop in elevation of 30cm per 300m of length. If sewage (assume the properties are the same as those of water) flows at a depth of 50cm in the pipe, what will be the discharge?
2.following results were obtained from consolidated undrained tests on specimens of a saturated normally consolidated clay
cell pressure kN/m2 100 200 300
ultimate deviator stress kN/m2 137 210 283
ultimate pore pressure kN/m2 28 86 147
Determine
a) effective stress strength parameters
b) undrained strength parameters
