Find the minimum diameter of a solid circular shaft if it has a maximum shear stress of 53 mpa and it is to transmit 28 kw of power at a rotational speed of 2,516 rpm. enter your numerical value below for minimum diameter, d, in units of millimeters. enter your answer to one decimal place and the result must be within +/- 1% of the correct value to be counted as correct.

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.
