Losses from lake A (left) feed lake B (right). The distance between them is 3.5 km. The water level in lake is 1100 m and in lake B is 1060 m. The coefficient of the permeability is 12.5 m/day. Find rate of the flow in the pore.

2. The following description is correct ( ).A. the denser the grid in the flow network, the smaller the hydraulic gradientB. two points on the same equipotential line, the pore water pressure is always the sameC. the same flow network, any two adjacent equipotential line between the potential energy difference is equalD. The direction of the infiltration flow rate is the direction normal to the flow line 3. In the triaxial shear test, the test that keeps the pore pressure of the soil sample at zero throughout the process from the application of the circumferential pressure until the soil sample is damaged is ( ).A. Unconsolidated undrained test B. Consolidated drained testC. Solidification without drainage test D. Solidification fast shear test
