Consider a room with the following dimensions: length x width x height = 6m x 6m x 3m. the atmospheric conditions are given as 34⁰c and 90 kpa, while the pressure of the water vapour is 1.8168 kpa. calculate the following: (a) the specific humidity (b) the relative humidity (c) if the air is cooled from its original condition to 10⁰c, determine whether condensation will take place, and if so, calculate the mass of condensate that will form.

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?

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way
