A 25-cm diameter oil line is buried with its centerline 60 cm below the ground. Assuming a soil temperature of 10 degrees Celcius and a soil thermal conductivity of .8 W/m-K, estimate the steady-state heat loss from the pipe (in W/m) when the oil is at 90 degrees Celcius.

(i) Ignore the inside thermal resistance
(ii) Recalculate your result if the inside heat transfer coefficient is 300 W/m^2-K.
