Chapter 3 Properties Of Pure Substance 纯物质性质
Summary
基础概念
- Liquid: compressed liquid 过冷水
- gaz: super-heated gaz 过热气
- phase change process 相变
- Saturation temperature 温度保和
- saturation pressure 饱合压力
- Satured Liquide 饱合液体
- Satured vaper 饱合气体
- Critical point 三相点
quality 质量分数
in the satured mixture region
理想气体
Ideal-gaz equation
- $PV = RT$
- constant of air: $R = 8.314 kPa\cdot m^3/mol\cdot k = \ pour\ air \ = 0.287 kPa\cdot m^3/kg\cdot k$
compressible factor 压缩系数
- $Z=\frac{P V}{R T}$
reduced pressure, reduced temperature 折算压力/温度
- 各种气体的性质又不相同,为了统一计算,这里引入折算压力\对比压力(reduced pressure)和折算温度\对比温度(reduced temperature),
- 其中$P{cr}$和$T{cr}$分别代表临界压力和临界温度
