Detailed Description

Implementation of the ideal gas law.

This class once initialized with either a pressure and temperature or a concentration and temperature will return the additional variable. Enjoy!

Usage details

In order to use this class, you first need to use one of the set_* options in order to initialize all the variables that define an ideal gas. In the set_* member function all properties are computed. If you would like to change, temperature, type of gas, etc. you will need to call this routine again. Once the set routine has been called, then you can request any gas property using get_* routines.

//Create a gas object
FuelCellShop::Material::Oxygen oxygen; 
//Create an object IdealGas
FuelCellShop::Material::IdealGas marc;
// Set all gas properties. Make sure you are entering the info using the correct units.
marc.set_pT_and_gas(101325, 298, &oxygen);
// You can now request info from your class.
double temperature = marc.get_T();
//Print to screen all properties
marc.print_properties_to_screen();
