II. In a gas turbine installation, shown in the Regenerator Fuel opposite figure, air is supplied at Pi of 1 bar and temperature Ti of 27 C intoa compressor which has a pressure ration t of 8. The air leaving the combustion chamber is heated up to a temperature T4 of 827 °C and expanded in a turbine up to a pressure Ps of 1 bar. A regenerator with an effectiveness ε of80 % is fitted at the turbine exit...
please solve the problem, it is thermo-design problem,
please do in details, thank you

The drill used by most dentists today is powered by a small air-turbine that can operate at angular speeds of 350000 . These drills, along with ultrasonic dental drills, are the fastest turbines in the world-far exceeding the angular speeds of jet engines. Suppose a drill starts at rest and comes up to operating speed in 2.0 . How many revolutions does the drill bit make as it comes up to speed? (Rev) Express your answer using two significant figures.
Question2 a. Referring to the effect on the thermodynamic cycle, explain how bleeding of air to cool turbine blades leads to improvement in engine performance, despite the fact that such bleed air undergoes minimal momentum change and thus contributes negligible thrust. A turbojet engine flies at Mach 2, and 60,000ft, whe the airflow is bled from the high pressure end of the compressor, which has a pressure ratio of 8:1. This bleed air is used to cool the turbine blades...
A jet engine propels an aircraft at 254 m/s through air at 39 kPa and 273 K.
