Question#1 I would like to compare a 100' length of 4" PVC pipe with air in it surrounded by Earth and/or water. What length of 4" copper pipe would equal a 100' length of PVC?
Question#2 If the inside of the pipe had turbulence what length of non-turbulent 100' PVC 4" pipe would it equal?
I do not know the equations that is why I am on this site. The EngineeringToolBox website states that copper is 400, PVC is .19, Earth is 1.5 and water is .58 thermal conductivity (k). The Earth and/or water surrounding the tube is 65°F Turbulence creates a ballpark of a 40% increase in heat transfer. I also read that water surrounding a tube is 4x times faster at transferring heat than the earth.
I appreciate any help as I am not an engineer.
