Heat Transfer Coefficient for a Buried Pipe Circulating Water

[lci]

I have a 6" buried carbon steel pipe with a small circulating hot water flow rate of 15 usgpm through it. I am looking for a reference to calculate the heat loss from the water through the pipe to the soil. The water enters at 180F and I would like to determine the heat loss so that I can size a heater to replace heat lost to the surroundings.

Does any body know a reference for this type of problem or a heat loss coefficient under these conditions?

Thanks

Yes. Post an email address. I have a page out of SimSci's pipephase manual that I think is exactly what you are looking for.

Can you please send me the Sim Scis pipe phase sheet showing the heat transfer from a buried pipe with circulating hot water to the ground. Thanks bob@wlc.ca

Just picked this link

from thread403-62540 of HVAC forum. Except pipe MOC I think this link would of help to you.

What you are not detailing is what is the condition of the soil? Is it dry, saturated, what type is it---
