The velocity of flow in a 25-m wide channel is given by u=u(y/h)^1/7 where h is the channel depth and y=0 denotes the channel bed. given that u=1.8 m/s and h 4 m, how many hours will it take to pass a volume of 1 million m3 through the channel?

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
