is a safety device commonly
used with a slotted nut.

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

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false
