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

What precautions should you take to prevent injuries when dealing with heavy loads?

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
