A standard vapour$-$compression cycle using refrigerant R$134$a as the working fluid

operates between the pressures of $140$ kPa $($evaporation$)$ and $800$ kPa

$($condensation$).$ If the mass flow rate of the refrigerant is $0\mathrm{.}05$ kg$/$s$,$

$3\mathrm{.}1$ Draw a p$-$h diagram of the cycle. $(2)$

$3\mathrm{.}2$ Analyse the cycle by evaluating:

$($a$)$ the rate of heat removal from the refrigerated space, $(4)$

$($b$)$ the power input to the compressor, $(5)$

$($c$)$ the heat rejection rate in the condenser, and
