About this exam

This is a 2024 final exam paper for engineering-thermodynamics-i at aau (industrial-engineering). This is a final examination for the Engineering Thermodynamics I course at the Addis Ababa Institute of Technology, administered in June 2024. The exam evaluates students' understanding of fundamental thermodynamic principles, cycles, and energy analysis. **Key Topics Covered:** Second law of thermodynamics, Carnot cycle and principles, entropy generation and transfer, geothermal power plant efficiency, and steady-flow compressor analysis using T-s diagrams and ideal gas properties. **Exam Structure & Format:** The exam is divided into two parts: Part I (15 points) consists of short answer and conceptual questions regarding thermodynamic laws and cycles. Part II (30 points) involves analytical problem-solving, including calculations for thermal efficiency, power generation, and compressor performance, supported by provided saturated water property tables.
