The specific gravity and void ratio of a soil sample are \(G\) and \(e\) respectively. The hydraulic gradient is

The intensity of active earth pressure in kPa at a depth of 10 m in dry cohesionless sand with an angle of internal friction of 25° and specific weight of 15 kN m^-3 is

A soil has a void ratio of 0.75 and a specific gravity of 2.66. The value of critical hydraulic gradient at which quick sand condition will occur is

The pressure that does not have any measurable influence on the void ratio or shearing resistance of the soil mass is

A homogeneous earthen embankment has an upstream water level of 12 m. The top width of the embankment is 3 m, and its upstream and downstream slopes (horizontal: vertical) are 2:1 and 2.5:1, respectively. A freeboard of 2 m is provided. The coefficient of permeability of the fill material is 2.5 × 10^-5 m.s^-1. If a 20 m long horizontal filter is placed inward from the downstream toe, the seepage discharge per unit length of the embankment is \(n \times 10^{-5}\) m³.s^-1.m^-1. The value of \(n\) is ______. (Rounded off to two decimal places)
