Extracted text: 2. Consider an ideal gas-turbine cycle with two stages of compression with intercooling. The overall pressure ratio is 9. The air enters each stage of the compressor at 300 K and of the turbine at 1300 K. Utilizing air-standard assumptions, determine the back-work ratio and the thermal efficiency of the cycle. 3. Consider an ideal gas-turbine cycle with two stages of expansion with reheating. The overall pressure ratio is 9. The air the compressor at 300 K and the air enter each stage of the turbine at 1300 K. Utilizing air-standard assumptions, determine the back-work ratio and the thermal efficiency of the cycle.
