Thermodynamic analysis of the gas parameters distribution under leakage from a closed volume with rigid walls

The work deals with the thermodynamic analysis of the parameters of the gas in a closed volume with rigid walls, during its leakage and heat exchange with the environment. Based on the first law of thermodynamics, the law of Fick and the equation of the gas state, we obtained an equation that charac...
