Athermodynamic analysis of a proposed brayton cycle gas turbine yields p=5 mw of net power production

The Brayton cycle is a thermodynamic cycle named after George Bailey Brayton that describes the workings of a constant pressure heat engine. The original Brayton engines used a piston compressor and piston expander, but more modern gas turbine engines and air breathing jet engines also follow the Brayton cycle.

The answer would be <5 and <7
