- Need to estimate the density and dynamic viscosity of such a mixed fluid: 80% Liquid Methane CH4 with solution of 20% Nitrogen Gas N2 with temperature of 94K and pressure of 1,467 hPa (the surface environment on Titan, the largest moon of Saturn).
- Will the effect of Nitrogen be ignorable to the composition's density and viscosity?
- When the chemists say composition with 80% A + 20% B, do you mean percentage by volume or by mass? sometimes it seemed assumed as a common sense in the paper, but non-chemist people may find it obscure.
Origin/Context: Table 1 of journal paper "Cassini radar observation of Punga Mare and environs: Bathymetry and composition". I tried wolframe alpha to give me an automatic answer, but its data base probably constrained to environment of earth. In situ data (to this date) does not exist for the liquid methane lake's fluid property on Titan, so we have to estimate it.
This might be too basic for any chemist, but I do find it quite difficult.
Appreciate any help!
