Heat generated by friction formula
WebWhen friction acts between two surfaces that are moving over each other, some kinetic energy is transformed into heat energy. Friction can sometimes be useful. WebMechanical seals generate heat as the primary ring and mating ring rub together. Heat is also generated through viscous shear of the fluid film between the faces and around the rotating components. For low viscosity fluids, most heat generation is by rubbing.
