The recommended time-weighted average air concentration for occupational exposure to water-soluble hexavalent chromium (Cr VI) is 0.05 mg/m3. This concentration is based on an assumption that the individual is generally healthy and is exposed for 8 hours per day over a working lifetime (that is from age 18 to 65 years). Assuming a body weight of 70 kg and an inhalation rate of 20 m3/h over the working life of the individual, what is the lifetime (70 y) CDI?

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.
