Finding the hydraulic characteristics of the Earth covering the broken pipe is going to be a guess at best. Would there be a simple correction factor or percent of found flow that could just be considered? God I love this stuff!
Additional information, Break area is fed by ground storage tanks and the zone is maintained by centrifugal pumps. Max HGL is 520ft and break site elevation is 325ft. Is there a speadsheet or some web tool that I can enter this data and gain the GPM's?
I'm looking to find the gallons per minute lost during a water main break. The information I have is this. 8 inch lined cast iron pipe. System pressure is 84psi. c-factor for the pipe is 100. The pipe was broken with a gap completely around the pipe of 1/4 of an inch. Gound cover is 4.5...
