Apower cycle operating at steady state receives energy by heat transfer at a rate qh at th = 1000 k and rejects energy by heat transfer to a cold reservoir at a rate qc at tc = 300 k. for each of the following cases, determine whether the cycle operates reversibly, operates irreversibly, is impossible. qh = 500kw, qc = 100kw qh = 500 kw , wcycle = 250 kw, qc = 200 kw wcycle = 350kw, qc = 150kw qh = 500kw, qc = 200kw
