Apower cycle operating between two reservoirs receives energy qh by heat transfer from a hot reservoir at th = 2000k and rejects energy qc by heat transfer to a cold reservoir at tc = 400k. for each of the following cases determine whether the cycle operates reversibly, irreversibly, or is impossible:
a.) qh 1200 kj wcycle 1020 kj
b.) qh 1200 kj qc 240 kj
c.) wcycle 1400 kj qc 600 kj
d.) η 40%
