Consider the binary eutectic copper-silver phase diagram in Fig. P8.22. Make phase analyses of an 88 wt % Ag−12 wt % Cu alloy at the temperatures (a) 1000°C, (b) 800°C, (c) 780°C + ΔT, and (d) 780°C − ΔT. In the phase analyses, include: (i) The phases present (ii) The chemical compositions of the phases (iii) The amounts of each phase (iv) Sketch the microstructure

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.

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.
