A vapor$-$compression A$/$C system uses R$134$a as the working fluid. The evaporator and condenser have pressures of $240$ kPa and $1000$ kPa $,$ respectively. The refrigerant enters the compressor with a mass flow rate of $0\mathrm{.}8k\frac{g}{m}in.$ The refrigerant leaves the compressor at $1000$ kPa and $60C$ and then leave the condenser subcooled by $5\mathrm{.}37C.[36$ pts$]$
