At a ski resort, water at 40 F is pumped through a 3-in diameter, 2000ft long, steel pipe from a pond at an elevation of 4286ft to a snow-making machine at an elevation of 4623ft at a rate of 0.26ft^3/s. It is necessary to maintain a pressure of 180 psi at the snow making machine. Determine the horsepower added to the water by the pump. Neglect minor loses.

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.
