Problem $4(10$ points$)-$ Energy balance in a compressor operating at steady state

Refrigerant $134$a enters an insulated compressor operating at steady state as saturated vapor at $-20C$

with a mass flow rate of $1\mathrm{.}2k\frac{g}{s}.$ Refrigerant exits at $700$kPa,$70C.$ Changes in kinetic and potential

energy from inlet to exit can be ignored. Please answer the following.

a$.$ Create a schematic for the compressor and show the interactions between the refrigerant and

the surroundings across the boundary.

b$.$ Using a T$-$v diagram, represent the process for the refrigerant. Is this a compression or an

expansion process? Why?

c$.$ Determine the volumetric flow rates at the inlet and exit, each in $\frac{m^3}{s}.$

d$.$ Considering states $(1)$ and $(2),$ would you claim that during the process the refrigerant behaves

as an ideal gas? Why?

e$.$ Compute the power input to the compressor, in kW$.$
