Bates (1992) suggests that inlet coefficients should not exceed 0.7 for adult salmonid fish passage, 0.5 for sites with marginal passage conditions, and 0.2 for juvenile salmonid passage. Entrance Loss Coefficients for Pipe or Pipe Arch Culverts

### Pressure Drop in Pipe Fittings and Valves - Katmar …

In long pipelines most of the pressure drop is due to the friction in the straight pipe, and the pressure drop caused by the fittings and valves is termed the "minor loss". As pipes get shorter and more complied the proportion of the losses due to the fittings and valves gets larger, but by convention are still called the "minor losses".

### What is loss coefficient in pipes? - Quora
