Increasingly, engineering education is responding to concerns about how engineering practice affects the environment. This text is the first to provide an integrated introduction to basic engineering topics and the social implications of engineering practice. Aimed at beginning engineering students, the book presents the basic ideas of thermodynamics, fluid mechanics, heat transfer, and combustion by relating the engine to the atmosphere. The book also discusses the greenhouse effect and the social implications of engineering in a crowded world with increasing energy demands. The book contains many problems and worked examples.
