Minor Losses
Minor Loss — Pipe Exit
Head loss as water discharges from a pipe into a reservoir, where the entire velocity head is dissipated. K is always 1.0 regardless of exit geometry.
Formula
hL = V² / (2g)
Resultlive
- Loss coefficient, K
- 1.00
- Velocity head, V²/2g
- 0.11468m
- Exit head loss, hL
- 0.11468m
Reference: Submerged-exit boundary condition: full velocity head is dissipated as turbulent kinetic energy in the reservoir.
