The building envelope of a glass skyscraper has an intricate system designed to limit thermal transfer, prevent air leakage, and repel moisture. Why would it require such complex design work compared to a structure with vinyl siding?
Buildings with vinyl siding are generally small enough that they do not need to be weatherized.
Glass has the lowest moisture resistance of any building material.
Structures with vinyl siding do not need to have a building envelope.
Traditional fiberglass insulation cannot be used with a transparent envelope.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
