Condensate Pipe Lines - Friction Resistance Imperial Units

Friction or major resistance in condensate pipe lines.

The table below can be used for running load. A common rule of thumb, if the start up conditions are unknown, double the running load to size condensate pipe lines.

Avoid friction resistance above 10 inches Water gauge - H2O - per 100 ft of pipe.

Example - Sizing Condensate Pipe

For a steam distribution system with a running load of 2000 lb/h - the startup condensate load is doubled to 4000 lb/h.

Using the 10 inch H2O column - a 1 1/2 inch pipe is acceptable.
