An air conditioner is designed to bring 10,000 ft3/min of outside air (90°F, 29.8 inches Hg, 88% relative humidity) to 40°F, thereby condensing a portion of the water vapor, and then to reheat the air before releasing it into a room at 65°F. Calculate the rate of condensation (gallons H2O/min) and the volumetric flow rate of the air delivered to the room. (Suggestion: On the flowchart, treat the cooling–condensation and the reheating as separate process steps.)

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?
