' Example 7—5 An engineering company is developing a new concept engine that draws heat at a rate of 700 KW from a new high temperature combustor at 2000 K and it rejects heat to the surroundings at 300 K. They measured the power output at 500 KW. For further improving the engine, the engineers want to know what percentage of the maximum possible power is produced by the currently engine ?
