Problem $12\mathrm{.}003-$ Analysis of reverse Carnot cycle

A steady$-$flow Carnot refrigeration cycle uses refrigerant$-134$a as the working fluid. The refrigerant changes from saturated vapor to saturated liquid at $\backslash (44\mathrm{.}00^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ in the condenser as it rejects heat. The evaporator pressure is $180$ kPa $.$

Problem $12\mathrm{.}003.$a $-$ Coefficient of performance

Determine the coefficient of performance. $($Round the final answer to three decimal places.$)$

The coefficient of performance is

Problem $12\mathrm{.}003.$b $-$ Heat absorbed

Determine the amount of heat absorbed from the refrigerated space. Take the required values from saturated refrigerant$-134$aTemperature table. $($You must provide an answer before moving on to the next part$).($Round the final answer to three decimal places.$)$

The amount of heat absorbed from the refrigerated space is Problem $12\mathrm{.}003.$c $-$ Work input

Determine the net work input. $($Round the final answer to three decimal places.$)$

The net work input is $\backslash (\backslash$quad $\backslash$mathrm$\{$kJ$\}/\backslash$mathrm$\{$kg$\}\backslash ).$
