Actually, this is a pretty standard test for many military and industrial applications, such as pressure testing boilers and other pressure vessels to verify integrity. It's done on a much more frequent basis on things like a fuel transfer line to verify leaks, which could have dire...
JKEngineering--Thanks! Unfortunatley, the 1-hour test needs to be conducted inbetween flight operations, so that it wouldn't realy be feasible to let the temperature settle out to more closely approximate that of the surrounding soil. I'm thinking that by treating the fluid as a "solid" for a...
racookpe1978--thanks. In fact, the temperature at a depth of 20 ft is about 69F year-round--near Las Vegas. The centerline of the pipe is at 55 inches, so that it experiences quite a bit of fluctuation depending on time of year, time of day/night, etc. The pipe is still going to be...
The line is a 12" OD--don't know the wall thickness at this point. Line contains hot JP8, and I'm trying to perform a heat transfer calculation on it as it releases heat to the surrounding soil--the centerline of the pipe is 55" below ground level. The fluid is undergoing a hydrostatic test...
Looking for a correlation for internal heat transfer for a horizontal circular pipe experiencing natural convection. The pipe contains jet fuel.
