WSAProperties 0.1.1

Package for calculating the properties of water/steam/air

WaterProperties. ML Automation of construction

Introduction

This library is a collection of functions for calculating various thermodynamic properties of water and steam. The library is based on the international formulation IAPWS (International Association for the Properties of Water and Steam) and allows for the calculation of properties of water and steam over a wide range of temperatures and pressures.

The module also is based on the following article:
Library of functions for calculating the properties of water and steam
Which is written in the Visual Basic programming language.

Quick Guide

Install library, use the pip install WaterProperties construct.
Using the library is as simple and convenient as possible:

First, import everything or needed functions from the library (use the from WaterProperties import * construct).
Second, you can use any function from the library (use the WaterProperties.Any_Function construct).

Example Usage

import WSAProperties

t = 25  # temperature in degrees Celsius
p = 101325  # pressure in Pascals

# calculate the density of water
density = WSAProperties.Density(t, p)
print("Density of water:", density, "kg/m^3")

# calculate the specific entropy of water
entropy = WSAProperties.Specific_Entropy(t, p)
print("Specific entropy of water:", entropy, "J/kg·K")

Functions

The purpose of each of the functions is contained directly in the name.
