Problem Sets

The following problems have been adapted from Cengel & Boles Thermodynamics: An Engineering Approach (McGraw-Hill). These problems are intended to both help illustrate the principles of thermodynamics and to familiarize students with the various features and capabilities of CyclePad. We have augmented the original problems to encourage students to explain their reasoning, demonstrate their understanding and draw conclusions about the numerical data.

• Chapters 1 & 2: table lookups, ideal gas, state postulate
• Chapter 3: heat transfer and work, boundary work, closed-system energy analysis; specific heats, D u, and D h of idea gases
• Chapter 4: control volumes, turbines and compressors, throttling valves, mixing chambers and heat exchangers
• Chapter 5 & 6: heat engines and thermal efficiency, refrigerators and heat pumps, Carnot heat engines and refrigerators, entropy changes
