At steady state, a power cycle develops a power output of 10 kw while receiving energy by heat transfer at the rate of 10 kj per cycle of operation from a source at temperature t. the cycle rejects energy by heat transfer to cooling water at a lower temperature of 300 k. if there are 100 cycles per minute, what is the minimum theoretical value for t, in k?
