A core task of engineers is to analyse energy related problems. The analytical treatment is usually based on principles of thermodynamics, fluid mechanics and heat transfer, but is increasingly being handled computationally. This unique resource presents a practical textbook, written for both undergraduates and professionals, with a series of over 60 computer workbooks on accompanying downloadable resources. The book emphasizes how complex problems can be deconstructed into a series of simple steps. All thermophysical property computations are illustrated using diagrams within text and on the downloadable resources.
