I need the answer as soon as possible
A) Problems Statement: Consider an ideal gas-turbine cycle with two stages of compression and two stages of expansion. The pressure ratio across each stage of the compressor and turbine is 10. The air enters each stage of the compressor at 300 K and each stage of the turbine at 2000 K. Assume isentropic operations for all compressor and the turbine stages and use variable specific heats (You need to get and calculate all thermodynamic properties from Thermodynamic Tables). Perform detailed analysis (Draw the cycle schematic and T-s diagram; find the turbine output work, compressor work, heat input, back-work ratio, thermal efficiency of the cycle) by considering the following scenarios: 1) Ideal Simple Brayton Cycle. 2) Ideal Regeneration-only Brayton Cycle. 3) Ideal one-stage compression (Intercooling only) Brayton Cycle. 4) Ideal one-stage expansion (Reheating only) Brayton Cycle. 5) Ideal one-stage compression and one-stage expansion (Intercooling+Reheating) Brayton Cycle. 6) Ideal one-stage Intercooling, one-stage Reheating, and Regeneration Brayton Cycle. 7) Ideal two-stages compression and two-stages expansion (Intercooling+Reheating) Brayton Cycle. 8) Ideal three-stages compression and three-stages expansion (Intercooling+Reheating) Brayton Cycle. 9) Repeat steps 1-8 by assuming non-ideal cycle (an efficiency of 90 percent for each turbine stage).
