Parvinbhai 

= = A pipe is buried underground during summer time, when the uniform temperature of the soil is Ti 20°C. Winter kicks in suddenly, and air at Too = -15°C with h 15 W/m²-K continuously blows over the ground for exactly 60 days. What minimum depth xm would you recommend burying the pipe at to avoid freezing. Hint: you will either have to use trial-and-error or the Excel Analysis Toolpack, which I can show you how to do.
