A refined thermal Reynolds equation considering conduction and convection modes of heat transfer across the film for inlet zone of the liquid lubricated strip rolling, developed by Bhatt and Sengupta, is applied in this analysis. It is known that inlet zone plays a dominant role in fixing the lubricant film thickness in the work zone. Hence, for the present analysis the effect of conduction and convection across the film in the inlet zone is studied on the work zone as well as the effect of variation of convection effect in the form of variation of the Peclet number. It is observed that the roll separating force and torque decrease with increasing the Peclet number.
