      In the cavitation model, unless otherwise specified, noncondensable gas is air with molecular weight 29.0. However, you can change the molecular weight of the non-condensable gas in the following command: (rpsetvar ‘mp/cvt/ncg-molecular-weight 32.0) In the above example, the molecular weight of the non-condensable gas is changed to 32.0. You can also check the molecular weight with the following command: (rpgetvar ‘mp/cvt/ncg-molecular-weight)
