The load capacity, attitude angle, and lubricant flow rate are computed using a modified Reynolds equation combined with the modified Coyne-Elrod boundary conditions. It was found that the pressure is decreased and the rupture point is shifted further downstream as the Reynolds number is increased or the surface tension parameter is decreased. Under a light loading condition, and a low surface tension parameter, a continuous film is approached.
