Web15.7 Use the virial equation to consider a mixture of propane and n -butane at 515 K at pressures between 0.1 and 4.5MPa. Verify that the virial coefficient method is valid by … WebOne form of the virial equation is the density series: pV ~ /RT = 1 + B(T)/V ~ + C(T)/V ~ 2 + . . . , (1) where p is the pressure, V ~ is the molar volume, T is the absolute temperature and R is the gas constant. The quantities B(T) and C(T) are, respectively, the second and third virial coefficients and are functions of temperature only.
