Pressure Drop
Pressure Drop (Line Loss) within the boiler is less
than the pipe rating of the pipe 9=ing used on the
boiler, so there is no appreciable, internal pressure
drop.
Explanation of GPM Flow
e following are given as examples of gallons
per minute water Eow required to deliver hot water
in order to provide heating of a given number of
degrees and at a certain BTU level:
500K BTU's at 20º F temperature di<erential
•
requires 50 gallons per minute.
250K BTU's at 20º F temperature di<erential
•
requires 25 gallons per minute
1M BTU's at 20º F temperature di<erential
•
requires 100 gallons per minute
As you can see from the above, with a 20º F
temperature di<erential, 10 gallons per minute of
Eow is required for each 100,000 BTU / Hour
transferred.
