Question $1.$ Consider a vapor$-$compression refrigeration cycle operating at steady$-$state, with Refrigerant $134$a as the working fluid. Use relevant information from the operational data given below:

States are numbered as in Textbook. Let the refrigeration capacity be $5\mathrm{.}2$ tons, and ignore heat transfer between the compressor and its surroundings. Sketch $\backslash ($ T $\backslash )-$s diagram of the cycle and determine:

$($a$)$ Mass flow rate of the refrigerant $(\backslash (\backslash$mathrm$\{$kg$\}/\backslash$mathrm$\{$min$\}\backslash )).$

$($b$)$ Isentropic efficiency of the compressor.

$($c$)$ Coefficient of Performance.
