Suppose that in a 2-dimensional crystallization process with only one substance, the nuclei do not all appear simultaneously, but rather appear uniformly over space and time at rate λ (nuclei per unit area per unit tim). a crystal only starts growing when the nucleus appears. adapt the k-a model to this situation: i. e., find φ(t). hints: work in a 3-dimensional space (2 dimensions of space and one of ti). consider an arbitrary point p in this space (arbitrary location, arbitrary time). determine the region, r, in this 3-dimensional space in which a nucleus must appear in order for p to lie inside the circle growing from the nucleus. then follow question 3 above.

Amanometer is used to measure the air pressure in a tank. the fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 34 in. if the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the
