Calculate the water vapor that will condense per cubic meter of wet air at 80% relative humidity and 40°c when it passes through an air conditioner at 10 °c. the vapor pressures of water at 10 °c and 40 °c are 9.2 and 55.3 mmhg. assume that the air coming out of the air conditioner at 10 °c is at 50% relative humidity.

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79

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?

The higher the astm grain size number, the finer the gran is. a)-true b)-false
