Aircraft powered by turbojet engine, gas turbine operates according to an ideal Joule$-$Bryton

cycle.

a$)$ Sketch the T$-$s diagram of the turbojet engine.

The core of the gas turbine has a compressor which compresses $36$ kg$/$s of air with a pressure ratio

P$2/$P$1=14.$ The air enters the compressor with P$1=30$ Kpa and T$1=240$ k$.$ Assume air as an ideal gas

with constant cp and k evaluated at $300$k$.[3]$

b$)$ Calculate the power that compressor requires in $[$Mw$].$
