Apipe of diameter 200 mm (constant) carrying water with an 5 mis and total head is density 1000 kg/m ) with velocity tpward slope. at a certain point, where the elevation is 5 m above a datum, the 21.5 m. a) determine the pressure of the pipe at 5m elevation. determine the pressure at elevation 10m (above same datum) if the of total head at 5m elevation.

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)
