A spool of copper wire has a starting diameter of D0 = 2.5 mm. It is drawn through a die with an opening that is 2.1 mm. The entrance angle of the die a = 18°. Coefficient of friction at the work-die interface is μ = 0.08. The operation is performed at room temperature. The pure copper has a strength coefficient K = 300 MPa and strain hardening coefficient n = 0.50. Determine (a) area reduction, (b) draw stress, and (c) draw force required for the operation.

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.
