A test plate 30 cm x 30 cm resting on a sand deposit settles by 10 mm under a certain loading intensity. A footing 150 cm x 200 cm resting on the same sand deposit and loaded to the same load intensity settles by

Cavitation is caused by

Flow at critical depth takes place in an open channel When

Two completely penetrating wells are located L (in metres) apart, in homogeneous confined aquifer. The drawdown measured at the mid point between the two wells (at a distance of 0.5 L from both the wells) is 2.0 m when only the first well is being pumped at the steady rate of Q₁ m³/sec. When both the wells are being pumped at identical steady rate of Q₂ m³/sec, the drawdown measured at the same location is 8, 0 m. It may be assumed that the drawdown at the wells always remains at 10.0 m when being pumped and the radius of influence is larger than 0.5 L Q₁/Q₂ is equal to

A footing 2 m x 1 m exerts a uniform pressure of 150 kN/m² on the soil. Assuming a load dispersion of 2 vertical to 1 horizontal the average vertical stress (kN/m²) at 1.0 m below the footing is
