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.

Friction losses may vary due to differences in hose construction resulting in fl ows different than those shown. For situations or lengths of hose not listed on the chart, approximate fl ows can be calculated using conventional hydraulics. WebNFPA monima wellness center
