tailieunhanh - POWER SYSTEM ANALYSIS AND DESIGN

In this book, we have used both MKS and CGS units. USCS units or FPS units used in the US Edition of the book have been converted to SI units throughout the text and problems. However, in case of data sourced from handbooks, government standards, and product manuals, it is not only extremely di‰cult to convert all values to SI, it also encroaches upon the intellectual property of the source. Also, some quantities such as the ASTM grain size number and Jominy distances are generally computed in FPS units and would lose their relevance if converted to SI. Some data in figures, tables, examples, and references, therefore, remains. | SI EDITION power SYSTEM ANALYSIS DESIGN J. DUNCAN GLOVER MULUKUTLA THOMAS J.
