It is known that the kinetics of some transformation obeys the Avrami equation and that the value of k is 6.0 × 10−8 (for time in minutes). If the fraction transformed is 0.75 after 200 min, determine the rate of this transformation.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.
