Which statement is false? The Rankine Cycle uses water as its working fluid while the Brayton Cycle uses air. Both the Brayton Cycle and the Rankine Cycle have phase change. The compressor in the Brayton Cycle is comparable to the pump in the Rankine Cycle Both Brayton cycle efficiency and Rankine cycle efficiency increase with a increase in burner operating pressure. Which statement is false? The Rankine Cycle uses water as its working fluid while the Brayton Cycle uses air. Both the Brayton Cycle and the Rankine Cycle have phase change.
