For gases the accepted difference between molar isobaric heat capacity and molar isometric heat capacity is the ideal gas constant
where Pt is the pressure of the tank, z is the compressibility factor, R is the universal gas constant
, Vt is the volume of the tank, Tt is the operating temperature, Pti is the initial pressure of the tank, and NH2 and MH2 stands for hydrogen moles per second passed to the tank and the molar mass of hydrogen gas, respectively.
