In the context of the engineering design process, what do engineers need to fully understand before they move forward with the design request? the specifications and limitations of the design request

the projects other engineers in the field are developing

the eventual end result of the project

the five basic engineering principles hii

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
