Q$\mathrm{.}2)$ Refrigerant R$134$a is compressed by a compressor of refrigerator. Inlet pressure and temperature of refrigerant is $0\mathrm{.}2$MPa and $0C,$ respectively. The exit pressure is measured as $1$ MPa. Mass flow rate of the refrigerant is $0\mathrm{.}05k\frac{g}{s}.$ Case a$)$ Assuming compression process is isentropic$,$ determine;

a$)$ Exit temperature of the refrigerant.

b$)$ Work consumed by the compressor

c$)$ Draw the process in $P-h$ diagram

Case b$)$ Assuming exit temperature is $75C,$ determine;

a$)$ Work consumed by the compressor

b$)$ Entropy generation

c$)$ Draw the process in T$-$s diagram

d$)$ Increase the compressor inlet temperature up to $20C$ parametrically and see the effect of temperature on work consumption. Please comment the result.

e$)$ Solve the problem for R$1234$yf and R$32$ refrigerants. Please comment the result.
