Your company has been asked to prepare a preliminary cost estimate for a three-story, 22,000 square foot office building. From projects you have constructed during the last year, you have determined that the average cost per square foot to construct an office building is $158.59. Using an inflation rate of 5 percent, prepare an estimate for the office building

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?
