A transformation is presented whereby a hydrostatic film pressure distribution p(x, y) for constant viscosity ν is transformed into a solution assuming ν = ν(p, T) in which T(x, y) satisfies the adiabatic energy equation. The effects of variable viscosity on film pressure profiles and load capacities are demonstrated by applying the transformation to simple hydrostatic bearing film geometries.
