Atank has two sides initially separated by a diaphragm. side a contains 1 kg water and side b contains 1.2 kg air, both at 20 celsius, 100 kpa. the diaphragm is now broken and the whole tank is heated to 600 celsius by a 700 celsius reservoir. find the final total pressure, heat transfer, and total entropy generation.

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?
