In some parts of the country, pumpkin launching is a favorite pastime during Halloween. You've designed a pumpkin launcher that launches the pumpkin at a height of h= 3 ft and want the pumpkin to impact the ground a distance d= 200 ft downfield. The launch speed is v0= 100 ft/s. What is the minimum needed launch angle and the corresponding total time of flight?

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.
