IF97

A Luau implementation of the IAPWS Industrial Formulation 1997 (IF97) for the thermodynamic and transport properties of water and steam, built for Roblox.

Installation

Download the rbxm file from the latest release or build it from source. Import the file into your Roblox project or sync it with Rojo.

Usage

Here is a basic example:

const IF97 = require("@game/ReplicatedStorage/IF97")

const p = 1000 -- pressure (kPa)
const T = 477 -- temperature (K)

const v = IF97.vpt(p, T) -- specific volume (m^3/kg)
const h = IF97.hpt(p, T) -- specific enthalpy (kJ/kg)
const s = IF97.spt(p, T) -- specific entropy (kJ/kg-K)

const Tsat = IF97.Tsat(p) -- saturation temperature (K)
const hf = IF97.hfp(p) -- specific enthalpy of saturated liquid (kJ/kg)
const sg = IF97.sgt(T) -- specific entropy of saturated vapor (kJ/kg-K)
