Apower cycle operating at steady state receives energy by heat transfer at a rate at 1800 k and rejects energy by heat transfer to a cold reservoir at a rate at 600 k. for each of the following cases, determine whether the cycle operates reversibly, operates irreversibly, or is impossible. a. q._h = 500 kw, q._c = 100 kw b. q._h = 500 kw, w._cycle = 250 kw, q._c = 200 kwc. w_cycle = 350 kw, q._c = 150 kw d. q._h = 500 kw, q._c = 200 kw.
