The kinetics of the austenite-to-pearlite transformation obey the avrami relationship.

using the fraction transformed–time data given here, determine the total time required for 95% of the austenite to transform to pearlite.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
