A 2.5 m wide rough continuous foundation is placed in the ground at 1 m depth. There is bedrock present at 1 m depth below the bottom of the foundation. The soil properties are c9 5 10.0 kN/m2 , f9 5 258, and g 5 18.0 kN/m3 . Determine the ultimate bearing capacity of the foundation.

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
