You are floating in a canoe down the wisconsin river moving with the current. assume that the flow is steady. (a) because the flow rate is steady, you do not accelerate as you float down the river.(b) because the river changes width and depth along its path, you accelerate as you float down the river.(c) you are continuously accelerating since the river is flowing downhill.(d) you will accelerate only if the flow becomes unsteady.

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)
