Write the type of chips generated at each of the following cutting conditions, and explain why. a. low cutting speed: b. large depth of cut: c. very high cutting speed d. low rake angle

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)
