As shown below, a refrigeration cycle condenses a flow of ammonia from a saturated vapor at 4 bar to a saturated liquid. The entering volumetric flow rate of the ammonia is 0.1 m³ /s. The ammonia functions as the cold reservoir for the refrigeration cycle, and the hot reservoir is at 25 °C. A faded specification sheet for the refrigeration cycle reads that the required power input is 35 kW. (a) Is this cycle possible? Why or why not? (b) If the cycle is impossible, how much work input is required to make the cycle possible? Hot reservoir at TH=25°C Woydle Ammonia P1 = 4 bar saturated vapor ác Ammonia P2 = 4 bar saturated liquid

Question

As shown below, a refrigeration cycle condenses a flow of ammonia from a saturated vapor at 4 bar
to a saturated liquid. The entering volumetric flow rate of the ammonia is 0.1 m3/s. The ammonia functions as
the cold reservoir for the refrigeration cycle, and the hot reservoir is at 25 ∘C. A faded specification sheet for the
refrigeration cycle reads that the required power input is 35 kW.
(a) Is this cycle possible? Why or why not?
(b) If the cycle is impossible, how much work input is required to make the cycle
