Acopper–silver alloy is heated to 900c and is found to consist of a and liquid phases. if the mass fraction of the liquid phase is 0.68, determine (a) the composition of both phases, in both weight percent and atom percent, and (b) the composition of the alloy, in both weight percent and atom percent

Consider airflow over a flat plate of length l = 1.5 m under conditions for which transition occurs at le = 0.9 m based on the critical reynolds number, re,e = 5 x 10. evaluating the thermophysical properties of air at 400 k, determine the air velocity. (hint: use the tables to find the properties of air)
