What is creep? what is stress relaxation?

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)

Steam enters a converging-diverging nozzle at 1.0 mpa and 500°c with a negligible velocity at a mass flow rate of 2.5 kg/s, and it exits at a pressure of 200 kpa. assuming the flow through the nozzle to be isentropic, determine: the exit area and (a) (b) the exit mach number
