magnus holmgren到python的xsteam表端口
XSteamPython的Python项目详细描述
xsteampython
将XSteam表移植到最初由magnus holmgren发布的python中。
xsteam根据IAPWS release IF-97提供蒸汽和水的特性。适用范围为0-1000巴和0-2000°C。
一些传输特性（热导率和粘度）也可用，并基于IAPWS 1998。
安装
有两种选择。首先是使用pip从pypi安装
pip install XSteamPython
或者通过克隆和运行
python setup.py install
要求
xsteampython只要求安装SciPy。
对于开发，所有依赖项都包含在requirements.txt中。

注意，调用stm.switchUnits()会从si变为英语单位，反之亦然。默认为国际单位制。
语法
函数调用的语法首先是所需的属性，然后是下划线，最后是输入属性。示例：
h_pT(101.0, 300.0)
该示例将返回给定压力（101 kpa）和温度（300°C）的焓。
