2. A 40° slope is excavated to a depth of 10 m in a deep layer of saturated clay of unit weight 20 kN.m3; the relevant shear strength parameters are cu = 70 kN/m2 and ?u = 0. The rock ledge is at a great depth. The Taylor's stability coefficient for ?u = 0 and 40° slope angle is 0.18. The factor of safety of the slope is :
3. A hydraulic turbine develops a power of 104 metric horse power while running at a speed of 100 revolutions per minute, under a head of 40 m. Its specific speed is nearest to one of the following :
4. The percentage error in the computed discharge over a triangular notch corresponding to an error of 1% in the measurement of the head over the notch, would be
Correct Answer: the difference in the slendeness ratio of the specimens
7. In a steady radial flow into an intake, the velocity is found to vary as (1/r2), where r is the radial distance. The acceleration of the flow is proportional to
