At steady state, a power cycle develops a net power output of 20kW while receiving energy by heat transfer at a rate of 20kJ per cycle of operation from a source at a temperature T. The cycle rejects energy by heat transfer to cooling water at a lower temperature of 540 K. If there are 190 (engine thermodynamic) cycles per minute, what is the minimum theoretical value for T, in K?Note: mm is the last
