"Hydrodynamics of Pumps" is Now in Japanese, Farsi, and Chinese Translation
Hydrodynamics of Pumps, a book written by Christopher E. Brennen, Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering, Emeritus, which was originally published in 1994 by Oxford University Press and Concepts ETI has now been published in Japanese, Farsi, and Chinese translations. Professor Tsujimoto composed the Japanese translation which was published by Osaka University Press. Most recently Cambridge University Press concluded an agreement with Jiangsu University Press for the publication (in both hardback and paperback) of the translation by Dr. Pan Zhongyong of Jiangsu University.
Compaction Bands in Sandstone are Permeable
José E. Andrade, Associate Professor of Civil and Mechanical Engineering, and colleagues have analyzed X-ray images of Aztec sandstone and revealed that compaction bands are actually more permeable than earlier models indicated. Their paper provides the first permeability calculations based on actual rock samples taken directly from the field in the Valley of Fire, Nevada. They conclude that these formations are not as impermeable as previously believed, and that therefore their ability to trap fluids—like oil, gas, and CO2—should be measured based on 3D images taken from the field.
