Apump creates a water pressure of 1 mpa in the supply line to a 65-mm-diameter, 300-m-long hose with a roughness height of 0.5 mm, the end of the hose is at an elevation 2.8 m higher than the beginning of the hose. the objective is to place a nozzle at the end of the hose that will create a jet of water that rises 15 mn into the air part a if the local head loss coefficient of the nozzle is 0.04, what nozzle diameter should be used? assume water at 20 c

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.

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
