A Refrigeration cycle, shown in Figure $2$ below, operates with mass flow rate of $3\mathrm{.}5k\frac{g}{s}$ R$134$a$,$ as shown in the

diagram below:

$2\mathrm{.}1.$ Determine the compressor power requirement

$2\mathrm{.}2.$ The energy expelled by the condenser

$2\mathrm{.}3.$ The energy absorbed by the evaporator

$2\mathrm{.}4.$ The coefficient of performance for this refrigeration cycle

$2\mathrm{.}5.$ Looking at the devices making up this cycle, which of the devices in the cycle works:

$($a$)$ Isobaric, $($b$)$ Adiabatic, $($c$)$ Isothermal, $($d$)$ Isometric, $($e$)$ polytropic, $($f$)$ isenthalpic
