$(10\%)$ Refrigerant $22$ enters the compressor of a vapor compression

refrigeration cycle as saturated vapor at $-40$ C with a volumetric flow rate of

$50\frac{m^3}{m}in.$ After compression, the refrigerant enters the condenser and

leaves it at $32$ C as saturated liquid. Assuming no pressure drop in the

condenser.

If the isentropic efficiency of the compressor is $90\%,$ find:

a$.(5\%)$ The power required by the compressor.

b$.(5\%)$ Plot the T$-$s and P$-$h diagrams to show the steps in the compressor

and the condenser.
