SUMMARY

The discussion centers on the search for an enthalpy calculator that incorporates pressure alongside mass and temperature for gas calculations. Users express frustration with existing calculators that only consider temperature and mass. A specific recommendation is made for the NIST software "STEAM," which provides thermodynamic properties for water, although its applicability to other gases remains uncertain. The need for comprehensive tools that include pressure as a variable is emphasized.

PREREQUISITES
  • Understanding of thermodynamic concepts, specifically enthalpy.
  • Familiarity with gas properties and variables such as mass, temperature, and pressure.
  • Knowledge of software tools for thermodynamic calculations.
  • Basic proficiency in using scientific calculators or software applications.
NEXT STEPS
  • Research the NIST "STEAM" software for its capabilities and limitations regarding gas enthalpy calculations.
  • Explore other thermodynamic calculation tools that include pressure as a variable.
  • Investigate online resources or databases that provide enthalpy data for various gases.
  • Learn about alternative software options for thermodynamic property calculations, such as REFPROP or CoolProp.
USEFUL FOR

This discussion is beneficial for chemical engineers, thermodynamics students, and researchers needing accurate enthalpy calculations for gases under varying conditions of pressure, mass, and temperature.

Hi,

Im after a calculator or software that can tell me the enthalpy of a gas.
I want something where I can enter the variables and have it tell me the enthalpy. The variables are mass (in moles), temperature and pressure.

So far I have seen ones that only use temperature and mass but not pressure.

Does anyone know where I can find one to use/download?

Even ones that must be paid for are fine.

Thanks for any help in advance.

see NIST software "STEAM" for thermo properties of water substance. I don't know if they have similar for other gasses
