Problem $06\mathrm{.}058-$ COP of heat pump using refrigerant

Refrigerant$-134$a enters the condenser of a residential heat pump at $800$ kPa and $\backslash (35^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ at a rate of $\backslash (0\mathrm{.}018\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$s$\}\backslash )$ and leaves at $800$ kPa as a saturated liquid. The compressor consumes $1\mathrm{.}250$ kW of power. Use data from the tables.
