Prior to replacing the condenser core on a 410A system in the refrigerator was recovered as a vapor and stored in the refillable cylinder

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 drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
