An ideal air standard brayton cycle operates at steady state with compressor inlet conditions of 300 K and 100 kPa and fixed turbine inlet temperature of 1700 K. for the cycle: a) determine the net power developed per unit mass flowing in kJ/kg, and the thermal efficiency for a compressor pressure ratio of 8
b) plot the net power developed per unit mass flowing , in KJ/kg , and the thermal efficiency, each versus compressor pressure ratio ranging from 2 to 50

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

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?

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
