Problem $2(18\mathrm{.}75p)$ : Problem $3(30p)$ : Refrigerant $-134$a enters the condenser of a residential heat pump at $700$ kPa and $40C$ at a rate of $0\mathrm{.}021k\frac{g}{s}$ and leaves at $800$ kPa as a saturated liquid. If the compressor consumes $1\mathrm{.}2$ kw of power, determine $($a$)$ the COP of the heat pump and $($b$)$ the rate of the heat absorption from the outside air? $($Show the heat pump cycle schematically$).$
