In a hydraulic system, moving oil has kinetic energy, which
is proportional to the square of the velocity of the oil. The
pump adds energy to the hydraulic

Losses in Pipe
It is often necessary to determine the head loss, hL,
that occur in a pipe flow so that the energy equation,
can be used in the analysis of pipe flow problems.
The overall head loss for the pipe system consists
