Air enters the heating section of an air-conditioning at 1 atm, 10 c, and 70 percent relative humidity at a rate of 35 m'/min, and it leaves the humidifying section at 20 c with a relative humidity of 90 percent. if the humidifier supplies wet steam at 100°c, determine (a) the temperature and relative humidity of the air leaving the heating section (b) the rate of heat transfer in the heating section

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

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?
