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

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

1.in one challenge on the titan games, competitors have to lift 200 pounds up a long ramp. angel is able to move the weight in 42 seconds. anthony gets it done in only 38 seconds. which statement is true? angel has more power than anthony. angel does more work than anthony. anthony does more work than angel. anthony has more power than angel. 2.a mountain climber exerts 41,000 j of work to climb a cliff. how much power does the climber need if she wants to finish in only 500 seconds? power = work / time 20,500,000 watts 82 watts 0.0122 watts 41,500 watts 3.your family is moving to a new apartment. while lifting a box 83 joules of work is done to put the box on a truck, you exert an upward force of 75 n for 3 s. how much power is required to do this? (hint: you only need two of the 3 numbers given! ) power = work / time 249 watts 25 watts 2075 watts 27.7 watts
