Very general relations are derived in compact form for fluid-film lubrication with variable material properties. Rigorous consideration of mechanical work leads to simple (and apparently novel) power dissipation formulas, one of which is particularly appropriate for finite element calculations. Comparison is made to previous results for the particular example of a flooded journal bearing.
