Calculate the radius of the largest interstitial void in the fcc ? iron lattice. the atomic radi- us of the iron atom is 0.129 nm in the fcc lattice and the largest interstitial voids occur at the (½,0,0), (0,½,0), (0,0,½), etc, type positions.

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)
