Coefficient of frictionGearsHersey parameterPower loss•Different coefficient of friction equations for gears were compared.•A new coefficient of friction equation is proposed to improve the existent method
The magnitude of the frictional force is often directly proportional to the normal force, or the force pressing the two surfaces against each other. The constant of proportionality varies depending on the surfaces which are in contact. For example, you might expect smaller friction when two "slick...
The drag coefficient CD is calculated by (Eqn. 23.32): (23.32)CD={24Re[1+0.15(Rep)0.687]Re<10000.44Re≥1000 where the particle Reynolds number Rep is defined as (Eqn. 23.33): (23.33)Rep=ρgdp|Ug−US|μg View chapter Book 2016, Pneumatic Conveying Design Guide (Third Edition)Wei Che...
What is the kinetic friction formula? The kinetic friction formula is an equation used to calculate the kinetic friction force acting on a moving object. It depends on the coefficient of friction and the normal force exerted on the object by the surface it is moving on. Friction force = co...
