06-22 an industrial wastewater has a flow of 1.5 mgd and a tss of 25 mg/l which is made up of only one size of particles (0.04 mm). the specific gravity of these particles is 2.2 and the temperature of the flow is 20c. (a) determine the overflow rate (in gpd/ft2) needed to remove 75% of these particles by settling. (b) calculate the area (in ft2) of the settling tank needed for this flow. (c) calculate the daily mass (in lb) of dry solids that must be disposed of from this process. assume the volume of sludge is negligibly small compared to the water flow. 2945 gpd/ft2, 509 ft2, 235 lb/d

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.
