A general fluid has pressure p [ random velocities ] and viscosity  [ interaction between particles ]. tex2html_wrap_inline1032 has the same interpretion as for dust except that tex2html_wrap_inline1054 and tex2html_wrap_inline1070 need no longer be zero in the MCRF. In particular tex2html_wrap_inline1054 represents heat conduction  and tex2html_wrap_inline1070 represents the stress forces  between adjacent fluid elements [ i'th component of force per area across a surface of constant tex2html_wrap_inline1124 ].
