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