CHE 3013, Fall 2010 1 of 14 Incompressible Fluid Flow Summary of Key Concepts and Skills Required for CHE 3013 Chapters 1, 2, 3, 5, and 8 Munson, Young, and Okiishi Fundamentals of Fluid Mechanics, 5 th Edition John Wiley & Sons, 2006 Chapter 1: Introduction Unit Systems 1. Chemical engineers must be able to work in both FPS (US Customary) and SI systems of units. 2. There is no standardized system of nomenclature. Variables have to be interpreted in the context in which they are used. 3. Find and keep a comprehensive list of unit conversion factors. There are some conversion factors inside the back cover of Incropera, et al., but these are probably not complete for our work. 4. Academia and literature SI 5. U. S. workplace FPS 6. 2 f m s lb ft lb 174 . 32 = c g (adequate precision for most cases, see p. 8) 7. Numbers without units are ambiguous and a major source of errors! Example: ( )( ) f lb 0.224809 0.45359237 9.80665 1 N 1 = = This should be written as f m 2 f 2 2 m 2 lb 0.224809 N 1 ft lb 174 . 32 s lb s ft 174 . 32 m 80665 . 9 s kg 0.45359237 lb kg 1 s m kg 1 N 1 = = =
