Moist air enters a cooling coil at 35°c dry bulb temperature and 55 percent relative humidity at a rate of 100 m/min, the air leaves at 27°c. calculate the capacity of the cooling coil in tonnes of refrigeration (tr) and the relative humidity of the air at the exit.

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?
