What is a monomer? how do they form a ploymer from the view point of chemical bonding?

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?

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)
