A steady$-$flow Carnot heat pump cycle uses ammonia as the working fluid. The refrigerant changes from saturated vapor to saturated liquid at $60\backslash$deg C in the condenser as it delivers heat, and leaves the condenser with a quality of $0\mathrm{.}05$ The evaporator temperature is $-10$C$.$ Show the cycle on a T$-$s diagram relative to saturation lines, and determine $($a$)$ the coefficient of performance, $($b$)$ the amount of heat delivered heated space, and $($c$)$ the net work input.

$($a$)$ the coefficient of performance, Answer $1$ Question $2$

$($b$)$ the amount of heat delivered to the heated space in kJ$/$kg Answer $2$ Question $2$

c$)$ the net work input in kJ$/$kg Answer $3$ Question $2$
