For the most engineering practices it can be assumed that pressure drop or head loss due to flow of fluids in turbulent range through valves and fittings is

### Experiment 5 - FAMU-FSU College of Engineering

This loss in pressure is mainly due to the fact that flow separates locally as it moves through such fittings. The pressure loss in pipe flows is commonly referred to as head loss. The frictional losses are referred to as major losses (h l) while losses through fittings, etc, are called minor losses (h lm).
