Hot Water Systems - Equivalent Length vs. Fittings Resistance
Equivalent length of fittings like bends, returns, tees and valves in hot water heating systems - equivalent length in feet and meter.
The minor loss in a system component can be converted to the "equivalent length" of a pipe or tube that would give the same major head loss.
Equivalent lengths of fittings like
- elbows - regular 90o, long radius 90o, regular 45o
- tees - line flow and branch flow
- return bends - regular and long radius
- valves - globe, gate, angle and swing check
- strainers
in hot water piping systems are indicated in the tables below.
Screw Fittings - equivalent length in feet
Equivalent length (in feet) of straight pipe for fittings like bends, returns, tees and valves. (Pipe size in inches)
Screw Fittings - equivalent length in meter
Equivalent length (in meter) of straight pipe for fittings like bends, returns, tees and valves.
Flange Fittings - equivalent length in feet
Equivalent length (in feet) of straight pipe for fittings like bends, returns, tees and valves.
Flange Fittings - equivalent length in metre
Equivalent length (in meter) of straight pipe for fittings like bends, returns, tees and valves.
