Document Summary
Basic concepts and techniques: vapor dome, thermodynamic table, ideal gas equations, polytropic process, boundary work, first law. Basic systems: piston-cylinder assembly (with springs and stops); separating chambers (mixing problem) Basic process: isobaric (piston-cylinder open to atmosphere); isochoric (piston at stops); polytropic (isothermal process in ideal gas) Practice: examples shown in class; assignments and tutorial problems; previous exams. Please refer to review 1 and review 2 on um learn for more details of what will be covered in chapters 1 -3 (the chapters before tt2). Closed system (no flow is involved, no h is involved) Pure substance (water, ammonia, r410-a, etc. vapor dome thermodynamic tables (p, v, t, u) Ideal gas (air, hydrogen, nitrogen, etc. ideal gas equations pv=rt u2 - u1= cv(t2-t1) Determine the boundary work and heat transfer: work: isobaric, linear spring, polytropic, heat transfer: 1q2=(u2-u1)+1w2. Two types of systems: open system (flow is involved, everything is about h)
