Ammonia enters the expansion valve of a refrigeration system at a pressure of \(10 \mathrm{bar}\) and a temperature of \(24^{\circ} \mathrm{C}\) and exits at 1 bar. If the refrigerant undergoes a throttling process, what is the quality of the refrigerant exiting the expansion valve?

ANSWER:

Solution 89P

Step 1 of 4

Ammonia expands through a valve from a known pressure and temperature to a given final pressure. So we need to find the exit quality ${X}_{2}$
