M^3/hr l/min l/sec us gpm uk gpm. This page provides a quick review of piping losses, starting with bernoulli's equation. Pipe friction pressure can be calculated excluding fr impacts.

Where, hl(vf) = valve/fitting head loss f = friction factor le = equivalent length v = fluid velocity d = pipe diameter g = gravitational constant.

This page provides a quick review of piping losses, starting with bernoulli's equation. It has been found experimentally that if the equivalent lengths for a range of sizes of a given type of fitting are divided by the diameters of the. In commercially available pipes the roughness is not as uniform and well dened as in the articially roughened pipes used by nikuradse. Equivalent length is the length of pipe with diameter and friction factor having the same energy loss as a fitting.
