A legacy system is all of the following, except:

Usually found on a mainframe.

A system that is already in place, from the past.

A system that often holds the middle tier of a multiple-tier system.

Old systems that often require hard-to-use command languages.

Systems that most often have detailed information that can be accessed by a system at a higher tier.

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.

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 is the major difference between thermoplastics and thermosetting plastics from the polymerization structure point of view?
