WebFriction Formulas Sheet & Tables. 1. Static friction (fs) Self adjusting in nature means magnitude of this is equal to external force applied on body and vary with external force. 0 ≤ f s ≤ µ s N. 2. Kinetic friction (fk) f k = µ … WebFRICTION LOSS (FL): PDP = NP +/-H + FL The next element in the PDP formula is friction loss (FL). When moving water comes in contact with the inner lining a hose, a loss of energy will occur due to friction. This energy loss is expressed in pounds per square inch loss. This friction results in an eddying of the water or turbulence within the hose.
