Minor Head Loss
Reference from the original Physics I textbook.
- Minor Head Loss
Minor head losses arise from fittings, valves, entrances, exits, and changes of pipe geometry. They represent mechanical energy loss per unit weight, measured in metres.

Head loss
Head loss describes a decrease in a flowing fluid’s mechanical energy per unit weight. Friction and fittings can produce losses that the ideal Bernoulli model omits. For example, a long rough pipe can require a greater pressure difference than a short smooth one to maintain the same flow.
