Resonant strumming of a taut cable with circular cross-section is observed at a flow velocity of 10 knots perpendicular to the cable. the diameter of the cable is 2 cm. what is the natural frequency of the cable? is this situation likely to become more serious at higher speeds?

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.
