Compare precipitation hardening (Sections 11.10 and 11.11) and the hardening of steel by quenching and tempering (Sections 11.5, 11.6, and 11.8) with regard to the following: (a) The total heat treatment procedure (b) The microstructures that develop (c) How the mechanical properties change during the several heat treatment stages

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)

What are the major differences between injection molding and extrusion?
