Minor Losses For Gravity Sewer: 

Contraction - Partial Flow
  • Calculate the head loss for a contraction in a gravity flow sewer pipe under partial flow.
Expansion - Partial Flow
  • Calculate the head loss for an expansion in a gravity flow sewer pipe under partial flow.
Contraction - Full Flow
  • Calculate the head loss for a contraction in a gravity sewer pipe under full flow/pressure flow conditions.
Expansion - Full Flow
  • Calculate the head loss for an expansion in a gravity sewer pipe under full flow/pressure flow conditions.
Bend
  • Calculate the head loss for a bend, with a deflection angle less than 40 degrees, in a gravity sewer pipe under full flow/pressure flow conditions.
MH - Straight Thru
  • Calculate the head loss for a straight thru transition in a manhole for a gravity sewer pipe under full/pressure flow conditions.
MH - Terminal
  • Calculate the head loss for a terminal manhole for a gravity sewer pipe under full/pressure flow conditions.
