Two humid air streams are adiabatically mixed at 1 atm pressure to form a third stream. the first stream has a temperature of 40°c, a relative humidity of 40 percent, and a volumetric flow rate of 3 l/s, while the second stream has a temperature of 15°c, a relative humidity of 80 percent, and a volumetric flow rate of 1 l/s. calculate the third stream’s temperature and relative humidity.

The “death throes” of stars are amongst the most complex phenomena in all of astronomy, and the “corpses” of stars amongst the most energetic and exotic objects in existence. beginning at the end of the core helium fusion stage in a star’s life, describe in detail the post-main sequence development of both (a) a 1.0 solar mass star, and (b) a 25.0 solar mass star. in what significant ways do they differ? what role does each of these types of stars play in the "star-gas-star" cycle and the evolution of chemical elements in our galaxy?
