Dimensional analysis can be used in problems other than áuid mechanics ones. the important variables a§ecting the period of a vibrating beam (usually designated as t and with dimensions of time) are the beam length l, area moment of inertia i, modulus of elasticity e, material density , and the beam cross-sectional area, so that t = fcn(l; i; e; ; a) recall that the modulus of elasticity has typical units of n/m2 . (a) find a dimensionless version of the functional relationship. (b) if e and i must always appear together (meaning that e

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.
