Seventy grams per second of air flows through a gas turbine, expanding from 1400 kPa to 101 kPa in a reversible polytropic manner. The air velocity at the inlet is 100 m/s at a temperature of 2200 K while the air velocity at the exit is 900 m/s. If the polytrpoic exponent n is 1.5. Determine the generated power, the rate of the heat transfer, the rate of the enthalpy change, and the rate of entropy change.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
