Air with a volumetric flow rate of 15,000 ft3/min enters an air-handling unit at 35oF, 1 atm. The air-handling unit delivers air at 80oF, 1 atm to a duct system with three branches consisting of two 26-inch-diameter ducts and one 50-inch duct. The velocity in each 26-inch duct is 10 ft/s. Assuming ideal gas behavior for the air, determine at steady state (a) The mass flow rate of air entering the air-handling unit (in lbm/s) (b) The volumetric flow rate in each 26-inch duct (in ft3/min) (c) The velocity in the 50-inch duct (in ft/s)

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.
