In laboratory tests conducted on a process slurry ,the velocity of the slurry measured at the distance of 75 m from the boundary is 1.125 m/s. the absolute velocity of slurry is found to be 0.048 pa s via viscometer tests and the slurry's relative density is 0.913 a. for this slurry, i. express the velocity in poise and in ns/m2 ii. what is the velocity gradient and shear stress at the boundary ? assume a linear velocity distribution b. the velocity distribution of a viscous liquid (dynamic viscosity u 0.9 ns/m*2 flowing over a fixed plate is given by u-0.68y-y 2 (where u-velocity in m/s and y-distance from the plate in m) determine the shear stresses at the plate surface ii. y 0.34 m
