Question One: A bullding is of 38.4m high and has plan dimensions 12.6m * 10m.
(a) Zone the vertical wall subjected to wind pressure, considering the breadth 'b' of the building
perpendicular to the wind direction as 12.6m, showing reference height 'z' to be taken at
different elevations. The total number of zones shall be restricted to four. Middle two
zones shall be of equal height.​

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

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?
