How does mining relate to geotechnical engineering

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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.
