You are moving 300 CCY per hour of material from the cut to the fill along a haul road that is 6,000 lf long. The dry unit weight of the material is 2,500 lb/CCY with a 12% water content. The elevation of the cut is 500 feet above sea level. The project manager anticipates the completion of the embankment, which is at an elevation of 900 feet, can be completed in 65 hours using a spread of 4 scrapers, 2 dozers, 1 compactor, and a water truck. What is the grade resistance as a percent when hauling from the cut to the fill

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.
