Summary

For a junior/senior-level course in Mechanical Engineering Technology, Mechanical Engineering, Heat and Mass Transfer, or Thermal System Design. Helping engineering technology and engineering students learn to design and analyze systems they many encounter in real-world practice, this comprehensive text provides a solid and rational introduction to the scientific, mathematical, and empirical methods for treating heat and mass transfer phenomena, and supplies the tools necessary for assessing and solving a variety of contemporary engineering problems. Graphic and straightforward in approach, it combines theory, real-world applications, experimental methods, and mathematical rigor to help students see the validity and relevance of concepts; highlights the convenience of various numerical methods to analyze more complicated situations involving heat and/or mass transfer; and helps students understand the relationship of heat and mass transfer to the disciplines of thermodynamics and fluid mechanics.
