Where is it recommended to have a higher mesh density? Mark all that apply Nowhere, the mesh should be uniform density throughout
Regions where a higher degree of accuracy is desired
Regions with large gradients in the primary variable
Regions of complex geometry

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.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
