Designed specifically for use in engineering technology programs, this popular text presents the fundamental concepts of thermodynamics and their practical applications to heat power, heat transfer, and heating and air conditioning. The text addresses real-world problems in engineering and design rather than abstract mathematics. New to this edition: *Inclusion of optional discussions on using Engineering Equation Solver (EES) as a commercial software tool for solving many of the problems encountered in thermodynamics and heat power *Addition of refrigerant blends R-407c and R-502 to the discussion of refrigerants in response to the increased applications of refrigerant blends in mechanical refrigeration *Expanded presentation of fuel cells Features of this text: *Unique optional Calculus for Clarity sections for students who have a background in differential and integral calculus *A consistent system of symbols and units that makes equal use of SI and English units in practice problems, example problems, and thermodynamic and property tables *An eight-chapter treatment of heat power/combustion/transfer and HVAC that is one of the most extensive available in a text at this level
