This popular book presents the fundamental concepts of thermodynamics and their practical applications to heat power, heat transfer, and heating and air conditioning. It addresses "real-world" problems in engineering and design -- "without" stressing abstract mathematics -- and uses a unique "calculus/non-calculus" based approach that ensures a rigorous treatment of each subject appropriate to the mathematics level of each reader. Includes a software package for doing cycles, combustion and radiation Heat Transfer problems with parametric analyses. Develops concepts and example problems in contexts that are based on "real world" applications. Offers unique optional "Calculus for Clarity" sections for readers who have a background in differential and integral calculus. Provides a complete introduction to convection, conduction, and radiation heat transfer; and examines application of thermodynamic principles to power-producing and consuming mechanical devices such as nozzles, pumps, turbines, gas and steam engines, heat pumps, and refrigeration systems. Features an eight-chapter treatment of heat power/combustion/transfer and HVAC (one of the most extensive available in a book at this level). For those in mechanical, manufacturing, industrial, and engineering technology interested in thermodynamics and heat transfer.
