Question: A flow net for flow around a single row of sheet piles in a permeable soil layer is shown in Figure 1. Given that k = 5 + 10-5 mm/sec Ya = 20 kN/m³ w = 21% n = 20% Determine, a) How high [m] the water will rise if piezometer is placed at point B (above point B). b) The total rate of seepage [m³/s/m] through the permeable layer per unit length. c) Magnitudes of effective vertical stress [kN/m²] at A and B.

Water at 20°C flows with a flow rate of (60+X) I/s from a large reservoir to a small reservoir through a 150 mm diameter cast iron piping system as shown in Figure A. Considering surface roughness value as 0.00026 m and kinematic viscosity as 1.004 x 10-6m²/s; determine the following: 1) Major and minor losses in the piping system 2) Elevation Z₁ in the larger reservoir Z₁=?

The flow net under a hydraulic structure has 5 flow channel with 10 equipotential drops. If the permeability of the bed material is 1.5 *10^-4 m/sec, find the quantity of seepage per meter width of the structure in m ^ 2 /sec under 3m head.

Refer to the cross section of the earth dam shown in the figure. Calculate the rate of seepage through the dam (q in m3/ min / m) using L. Casagrande's method.
