What is CCS (three word answer expected). For the third word I often refer to it as sequestration (but due to the negative connotation of the use of this word in budgets, the terminology use has been discontinued by many governments). I am looking for the alternative S word here.

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.
