Afluid of 100c flows with a free-stream velocity of 1m/s along a 5m long flat plate. compute the average drag coefficient and the drag force acting per 2m width of the plate over a distance of 0.6m from the leading edge for the following fluids (a)air, and (b) n2

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)
