Python Thermo库中的混合功能

发布于 2025-02-08 03:37:40 字数 385 浏览 2 评论 0原文

我正在尝试使用Python中的Thermo库，并想计算“石灰牛奶”和水的组成，但是当我在下面运行代码时：

from thermo.chemical import Mixture
mix = Mixture(['water', 'Ca(OH)2'], Vfls=[.6, .4], T=300, P=1E5)
print(mix.Cp)

当我查看Thermo Data时，我会遵循错误的错误

TypeError: unsupported operand type(s) for /: 'float' and 'NoneType'

，这似乎是'CA的某些属性（哦）2'没有，我是否假设水中有问题，而'ca（oh）2'可能是混合物吗？

I am trying the thermo library in python and want to calculate composition of 'milk of lime' and water however when I run the code below:

from thermo.chemical import Mixture
mix = Mixture(['water', 'Ca(OH)2'], Vfls=[.6, .4], T=300, P=1E5)
print(mix.Cp)

I get following error

TypeError: unsupported operand type(s) for /: 'float' and 'NoneType'

When I looked into thermo data it seems like some of the properties for 'Ca(OH)2' is None, am I assuming something wrong in water and 'Ca(OH)2' can be a mixture?
