Awindow consists of two 4mm thick glass (k = 0.26 w/mk), separated by 12 mm stagnant air layer (k = 0.26 w/mk) and encased in a 2.5 cm thick steel frame (k = 43 w/mk). if the frame cross-sectional area is 5% of the total area, then for any given temperature difference, the percentage of the total heat flow rate that passes through the frame is

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)
